Help restricting non whole numbers in a script

I am working on a script that asks for an input to be given between 1 and 100. I would like to have the restriction that the input is limited to between 1 and 100, and that the number must be a whole number.Here is the code:

number=input('Enter a whole number between 1 and 100:')

while number<1 || number>100

display('Not a valid number please try again')

number=input('Enter a whole number between 1 and 100:')

end

I can't figure out how to get it to set a restriction to non-whole number values. Please let me know how to specify this. I have been searching for a while and haven't found the solution.

A very easy check is just:

rem(number,1) ~= 0

So if number has a fractional part, then rem(number,1) will return that fractional part. Then I tested to see if the fractional part was zero.

Slightly shorter is just

~rem(number,1)

but that is I think less obvious. Try it out though. What does that code fragment return when number has a fractional part? Does it return true or false? What does it do when number is a pure integer?
