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. Is there a function, or a way I can do that?

Thanks in advance!

Answer 1

double x=22.336;
int y=(int)x;
double d=(int)((x-y)*1000);

this should work
