I am trying to round the value of an expression to two decimal places while keeping any trailing zeros. For example, I would like 36.397 to round to 36.40, not 36.4. I have tried writing the following code, but it always removes any trailing zeros:
Output(4,13,round(100/X,2))
Is there any other way to round numbers using commands on a TI-84 calculator? Any code that changes the rounding settings of the calculator from "FLOAT" to "2" would also work for me.
For anyone else wondering, it is possible to adjust the rounding settings of the calculator by simply using Fix followed by the number of decimal places to round to (in my case, Fix 2). Using Float reverts the rounding settings to remove trailing zeros.

I am trying to add two zero place holders in front of a field without changing the actual values involved. The field is an order number that is being pulled from MOMs. So right now that fields' formula is {cms.ORDERNO}.
When I try '00'+{cms.ORDERNO} the field displays 001,254.00. How can I remove the decimals and comma so it displays 001254?
The usual trick is to pad with plenty of extra digits on the left and then only take the six you really want from the right. This would handle any order number ranging from 1 to 999999.
right("000000" + totext({cms.ORDERNO}, "0"), 6)
When you don't specify a format string, as you tried, it uses default settings which usually come from Windows. By the way, if I recall correctly cstr() and totext() are equivalent for the most part but totext() has more options.
You should also be able to specify "000000" as the format string to produce the left-padded zeroes. Sadly I don't have Crystal Reports installed or I'd check it out for you to be sure. If this is the case then you probably don't need a formula if you just want to use the formatting options for the field on the canvas. If you do use a formula it's still simple.
totext({cms.ORDERNO}, "000000")
You definitely want to use the Replace formula a few times for this. The formula below converts ORDERNO into string, removes any commas and trailing decimal places, then adds the two zeroes at the beginning:
`00` + REPLACE(REPLACE(CSTR({cms.ORDERNO}),".00",""),",","")
So for example, if cms.ORDERNO is 1,254.00 the output from this formula would be 001254
I know this is older, but better solutions exists and I ran across this same issue. ToText has what you need built right in.
"00" + ToText({cms.ORDERNO}, 0, "")
From the Crystal Documentation:
ToText (x, y, z)
x is a Number or Currency value to be converted into a text string; it
can be a whole or fractional value.
y is a whole number indicating the number of decimal places to carry
the value in x to (This argument is optional.).
z is a single character text string indicating the character to be
used to separate thousands in x. Default is the character specified in
your International or Regional settings control panel. (This argument
is optional.)
These two long numbers are the same except for the last digit.
test = [];
test(1) = 33777100285870080;
test(2) = 33777100285870082;
but the last digit is lost when the numbers are put in the array:
unique(test)
ans = 3.3777e+16
How can I prevent this? The numbers are ID codes and losing the last digit is screwing everything up.
Matlab uses 64-bit floating point representation by default for numbers. Those have a base-10 16-digit precision (more or less) and your numbers seem to exceed that.
Use something like uint64 to store your numbers:
> test = [uint64(33777100285870080); uint64(33777100285870082)];
> disp(test(1));
33777100285870080
> disp(test(2));
33777100285870082
This is really a rounding error, not a display error. To get the correct strings for output purposes, use int2str, because, again, num2str uses a 64-bit floating point representation, and that has rounding errors in this case.
To add more explanation to #rubenvb's solution, your values are greater than flintmax for IEEE 754 double precision floating-point, i.e, greater than 2^53. After this point not all integers can be exactly represented as doubles. See also this related question.
i have code and use double function several time to convert sym to double.to increase precision , I want to use digits function.
I want to know it is enough that I write digits in the top of code or I must write digits in above of every double function.
digits set's the precision until it is changed again. Calling digits() without any input you get the precision to verify it's set correct.
In many cases digis has absoluetly no influence on symbolic variables because an analytical solution is found. This means there are no precision errors unless you convert to double. When convertig, digits should be set to at least 16 because this matches double precision.
FormatCurrency(
(SUM(iif(IsNothing(Fields!Planned.Value),0,Fields!Planned.Value))-(SUM(iif(IsNothing(Fields!Actuals.Value),
iif(IsNothing(Fields!Forecasts.Value),0,Fields!Forecasts.Value),
iif(Fields!Actuals.Value=0,iif(IsNothing(Fields!Forecasts.Value),
0,
Fields!Forecasts.Value),Fields!Actuals.Value))))),
iif(Parameters!DecimalDigits.Value=1,1,iif(Parameters!DecimalDigits.Value=2,2,0)),0,0,0)
)
this is my expression which is returning negative values and how to remove this negative sign in front of the number
The easiest way is to turn the expression around. For instance, if
Planned - Actual
is giving you negative numbers and you want positive numbers then maybe you want
Actual - Planned
Otherwise you could just take the whole expression away from zero to reverse the sign:
0 - <expression>
Or if you really want to kill the negative sign regardless, then use Absolute - this returns the value as a positive number regardless
Abs(<expression>)
I would also remove the formatting part of the expression and put that into the Format property. Almost everything in SSRS can be an expression, so you don't have to do everything in the Value expression.
I'm a complete novice to objective C/ipad development, but I am trying to build a simple four function calculator on the iPad.
My problem is trying to display a number with a decimal in it: i.e. 5.273 or .0021
My entire calculator is float, but when doing
[resultfield setText: NSString stringWithFormat:#"%lf", display]]
the output (say the one button was pressed) would be: 1.00000. I know that if you change the format to #".0lf" all the extra zeroes will disappear and the output would be 1
However, that doesn't help me when doing trying to input a decimal number, or when doing division. If I divide 10/3 the result would be displayed as 3 rather than 3.333333333
Any ideas on how to keep my numbers as float but not display trailing zeroes?
Check out the NSNumberFormatter class. It will let you set rounding and truncation of your decimals.
