I am creating a script converting a csv file in an another format.
To do so, i need my numbers to have a fixed format to respect column size : 00000000000000000,00 (20 characters, 2 digits after comma)
I have tried to format the number with -f and the method $value.toString("#################.##") without success
Here is an example Input :
4000000
45817,43
400000
570425,02
15864155,69
1068635,69
128586256,9
8901900,04
29393,88
126858346,88
1190011,46
2358411,95
139594,82
13929,74
11516,85
55742,78
96722,57
21408,86
717,01
54930,49
391,13
2118,64
Any hints are welcome :)
Thank you !
tl;dr:
Use 0 instead of # in the format string:
PS> $value = 128586256.9; $value.ToString('00000000000000000000.00')
00000000000128586256.90
Note:
Alternatively, you could construct the format string as an expression:
$value.ToString('0' * 20 + '.00')
The resulting string reflects the current culture with respect to the decimal mark; e.g., with fr-FR (French) in effect, , rather than . would be used; you can pass a specific [cultureinfo] object as the second argument to control what culture is used for formatting; see the docs.
As in your question, I'm assuming that $value already contains a number, which implies that you've already converted the CSV column values - which are invariably strings - to numbers.
To convert a string culture-sensitively to a number, use [double]::Parse('1,2'), for instance (this method too has an overload that allows specifying what culture to use).
Caveat: By contrast, a PowerShell cast (e.g. [double] '1.2') is by design always culture-invariant and only recognizes . as the decimal mark, irrespective of the culture currently in effect.
zerocukor287 has provided the crucial pointer:
To unconditionally represent a digit in a formatted string and default to 0 in the absence of an available digit, use 0, the zero placeholder in a .NET custom numeric format string
By contrast, #, the digit placeholder, represents only digits actually present in the input number.
To illustrate the difference:
PS> (9.1).ToString('.##')
9.1 # only 1 decimal place available, nothing is output for the missing 2nd
PS> (9.1).ToString('.00')
9.10 # only 1 decimal place available, 0 is output for the missing 2nd
Since your input uses commas as decimal point, you can split on the comma and format the whole number and the decimal part separately.
Something like this:
$csv = #'

I do things like this all the time, usually for generating computernames. That custom numeric format string reference will come in handy. If you want a literal period, you have to backslash it.
1..5 | % tostring 00000000000000000000.00
00000000000000000001.00
00000000000000000002.00
00000000000000000003.00
00000000000000000004.00
00000000000000000005.00
Adding commas to long numbers:
psdrive c | % free | % tostring '0,0' # or '#,#'
18,272,501,760
"Per mille" character ‰ :
.00354 | % tostring '#0.##‰'
3.54‰
I have the following Powershell variable
$var = "AB-0045"
I would like to increase the number in the string to become "AB-0046".
I can do:
$newNumber = [int]$var.Substring($var.length -4,4) + 1
Which will give me the desired number 46, but then I have to append that 46 as a string to a new string "AB-00".
Is there a better way to do that?
Now that you have the integer, you'll have to convert back to string formatted in the way you'd like and concatenate.
I'd recommend adding to "AB-" rather than "AB-00" in case your number goes over 100.
To pad leading zeros, you can use the -f operator.
e.g. "{0:d4}" -f 45
You'll still need to get the integer first (45 in the example) from your original string.
I tested with regex class Replace() method and string class Split() method with string formatter. Split() seems faster provided your string is always in the same format. The Replace() method does not care what happens before the last 4 numbers:
# Replace Method
[regex]::Replace($var,'\d{4}$',{([int]$args[0].Value+1).ToString('0000')})
# Split method
$a,[int]$b = $var.split('-'); "{0}-{1:0000}" -f $a,++$b
Trying to convert the number numeric value in this string to a percent. Is there any easy way to do this in powershell?
"Percentage of records ","0.02"
So, the output would look like :
Percentage of records , 2%
Thanks in advance for any suggestions you can provide.
Yes, you can convert the string to a float data type (single, double, decimal), and then convert it back using a format string, like so:
"Percentage of records ", ([double]'0.02').ToString('P0')
And if you want it to output in a single line, you could use:
"Percentage of records: $(([double]'0.02').ToString('P0'))"
Explanation:
Convert your string to a float datatype: [double]'0.02'
Convert that float back into a string: .ToString()
But we want to format it as a percentage, so we supply P0 as a parameter.
i. P - means to format the value as a percentage, this performs the N * 100 operation for you and then adds on the percent sign
ii. 0 - controls the number of decimal places to show. In your case, you want to show zero decimal places.
Note: The percentage format string will round your value to the nearest decimal that you specify.
Example:
0.021.ToString('P0')
# returns 2%
0.025.ToString('P0')
# returns 3%
As #mklement0 pointed out in the comments. I hadn't considered that your sample may be a single string, like:
'"Percentage of records ","0.02"'
I assumed it was two strings, which you separated with a comma.
In the event it is a single string, then you need to extract the number to use it. Once you have isolated the number, then you can use my advice above:
$yourString = '"Percentage of records ","0.02"'
# probably the more "proper" way
$pctValue = ($yourString -split ',' -replace '"')[1]
# or
# a hacky way I just thought of that happens to work in this scenario
$pctValue = (iex $yourString)[1]
Explanation of first example:
-split ',' - Take the string, and break it out into multiple strings, separating them by comma
-replace '"','' - Replace all instances of " with blank. The second parameter is optional since you are removing. Could be written as -replace '"'
(...)[1] - This is saying to take the SECOND string that it returned (starts at zero). In this case it would be your 0.02 value.
Explanation of second example (this is a bit of a hack, but thought it would be fun to include anyway):
iex - alias for Invoke-Expression - it's telling powershell to run whatever is inside of the string verbatim. So it's the equivalent of typing "Percentage of records ","0.02" into powershell and hitting enter. Which in PowerShell terms, that is the equivalent of passing it a list of strings.
Use -f (format operator) in powerhsell for build your string :
"Percentage of records, {0:0%} " -f 0.02
or in percentage :
"Percentage of records, {0:P0} " -f 0.02
We need to convert a plain number to a currency value. However, nothing we find seems to work.
We tried the basic code below, but that returns a value of $123,456.00 when it should be $1,234.56.
$rawNumber = 123456
$newNumber = 0
$newNumber = "{0:c}" -f $rawNumber
We tried different iterations of "{0:c}" (c2, c1,etc), but it always returns a number, but just adding zeroes on to the end.
We tried converting the number to a string and inserting the decimal, commas and dollar sign, but we're dealing with numbers that can be as short as two or as long as ten, so it becomes something of a beast to try and plan for every possible combination.
Are we missing something obvious to easily convert numbers to a currency value?
Thank you for any help you can provide.
If you have a subdivision of the primary unit of a currency, you need to divide the input value to get the number of primary units, in this case:
$dollars = $rawNumber / 100
$formattedString = '{0:C}' -f $dollars
Beware that the resulting formatted string will depend on the current locale. You can pass a [cultureinfo] object to the ToString() method of the target object instead if you want a specific locale enforced. Here shown with en-US, de-DE and da-DK:
PS C:\> 'en-US','de-DE','da-DK' |ForEach-Object { $dollars.ToString('C',[cultureinfo]$_) }
$1,234.56
1.234,56 €
1.234,56 kr.
You can format the input using {0:C2} the 2 in C2 is the amount of decimal places.
Example:
$rawNumber = 123456
$newNumber = 0
$newNumber = "{0:C2}" -f $rawNumber
I need to add decimal to an integer.
Eg:
Amount = 12345
The output should be
Amount = 123.45
Could someone help me how to achieve this using power shell
Always use a comma if you're looking to format a long string, adding a decimal point implies the number has a decimal component.
(12345).ToString("N0")
12,345
the N0 is a default formatting string which here gives the comma separated string.
if you're looking to fix badly stored decimal numbers or something where your question is actually what you're looking for, dividing by 100 will work for your needs.
12345 / 100
123.45
if you need a more code based solution which handles trailing zeroes or something you could use this:
$num = 12345
$numstr = "$num"
$splitat = $numstr.Length - 2
$before = $numstr.Substring(0,$SplitAt)
$after = $numstr.Substring($SplitAt)
"$($before).$($after)"
or this
"12345" -replace '(\d*)(\d{2})','$1.$2'
