Simple but great. Really practical kata.

Python 2 will perform floating point division if either the divisor or divident is floating point. Constants are floating point if you include a decimal point. 4 is an int. 4.0 a float. Or you could cast an int variable to float with a float().

loops!

since this works, and meets the description, and what I did... it's funny, that the obvious isupper() got so much attention when it does not work with non alpha inputs.

solved
it turned out i needed 'Using'... kingda imports

Not an issue. Your code is the cause of the error.

stupid challenge couldn't do rounding to finish. used different methods and discovered :>>

src/Solution.cs(12,20): error CS0103: The name 'Double' does not exist in the current context

something like this. tryed different methods that also don't work.
if it is not bugged and challenge it is real then it could be written in description.

If the value entered in the function is not a string, well, you know where that variable should be sitting

Cryptic sentences =/= specifications.

No random tests.

i didn't get the first parameter of the sub() function of regex..i used thr same function tho but i did it in a different way

Thank you, I wasn't sure what was mentioned error about, therefore I asked :)

Read my post below, it's been explained there.
