Double values are not printed with zeroes after the decimal point if those zeros have no mathematical importance.
Printing 55.0 will just print "55". That is to quote the documentation:
The representation is a number literal such that the closest double value to the representation's mathematical value is this double.
In other words, "55" is the simplest form of "55.0" there is. Mathematically, you could also say it's "55.00" or "55.000" or even "55.00000000000". It doesn't change.

When i convert String values to Double, if the decimals are zeros (for example 10.0,11.0 etc), swift automatically rounds the number and removes the decimals. Is there a way to prevent swift from removing the zeros after the decimal point?
I gave it a try in the online compiler that repl.it provides. But it doesn't act the way you said. I wrote the following code:
let x = Double("10")!
print(x)
And the output I got was:
10.0

Is there any opposite function of "primes" in matlab?
(Primes : Prime numbers less than or equal to input value)
What if i want to find greater than or equal to input value?
Thank you.
You always have to provide an upper limit. If you wanted prime numbers "greater than or equal to the given value," they would go to infinity.
I would suggest starting with "less than or equal to," provide the function with an upper limit, and then use a conditional to filter out those that are too small.

Newbie's question: What does $matrix[$row][4]=1; mean in a code? The row and column are known to me. Why is it made equal to 1?
The command will set the cell at position $row,4 with the value 1
= is the assignment operator in Perl. It assigns the value 1 to the cell at the coordinates $row, 4.
The comparison operators for equiality are eq for strings and == for numbers.

i have to do huffman coding on a message read from a file,in Matlab.For that i have to find the probability occurrence of each alphabet in that message.Using that frequency i have to do huffman encoding.Can you please specify how to read a message from the file and store it as a string for the same purpose..Can anyone help me to solve this
What you need is a histogram count:
counts = histc(lower(x), 'a':'z');
where the output count contains the number of occurences for each letter in the message string x. For instance, the first element count(1) corresponds to the number of occurrences of a, count(2) corresponds to the number of occurrences of b, etc...
Also note that this x is converted to lowercase o make the counting case insensitive.

I need to type some matrix containing both letters and numbers.
Something like list=["a" 1;" b" 2; "c" 3; "d" 4; "e" 5; "f" 6; "g" 7]
Can anybody give me some tip?
If you want "just" a mix of strings and numbers, use a cell array. See the MATLAB documentation here.
If you're trying to set up some kind of map/hash, you want a MATLAB "structure." See the documentation for that here.
