Is there a function that return a decimal point value from a double/float ?

Question

Maybe there's a function that I don't know, that works a little bit like this:

double x = 699.25;
int n = getPoint(x);
std::cout << n; //outputs 25

You get the point (:p). Is there a function, or a way I can do that?

Thanks in advance!

Answer 1

No function that I know of, but if you want to extract floating point you can do something like this:
double x = 699.25
double y = x - (int)x; // 699.25 - 699
Then you are left with 0.25 or any floating point number you want. If you wanna get rid of "0." you can multiply number by 100, or use "to_string" method and then delete first 2 characters from front.

Catch the case that the number does not have decimal part
