I'm a beginner in C programming, but I want to know if there is a function that can be used to determine if a float ends in a particular number. In pseudo code it would look something like: X * Y = Z IF Z ends in 0.5 {...} ELSE {...} or X * Y = Z IF Z ends in 0.2498 {...} ELSE {...} I've searched around but I can't find anything. This is probably because I don't know the function's name to find more information about it. This is C programming, not C++. Thank you!

C Programming - If float ends in ... do ...?

I'm a beginner in C programming, but I want to know if there is a function that can be used to determine if a float ends in a particular number. In pseudo code it would look something like:

X * Y = Z

IF Z ends in 0.5 {...} ELSE {...}

X * Y = Z

IF Z ends in 0.2498 {...} ELSE {...}

I've searched around but I can't find anything. This is probably because I don't know the function's name to find more information about it.

This is C programming, not C++. Thank you!

Update:

That's not really what I was looking for, but you gave me an idea that would fix my program!

Thanks so much :D
