Floating point decimal movement

Unregistered · 03-17-2002

Hey guys,

I was wondering how i could round a floating point number. I know how to do it with the print function but i need to do it in a calculation:

for example I would like the number 0.009999 to say .01

thanks

This should work, I didn't test it though.

Code:

double round ( double value, unsigned decimal )
{
  return ceil ( value * pow ( 10.0, decimal ) + .5 ) / pow ( 10.0, decimal );
}
