I am having a terrible time trying to do something that should be easy. I have a NSNumber value of 32025.89 seconds. I need to represent that in Hours, Minutes, Seconds. Is

Answer 1

Here's a way without any libraries except for modf() from math.h:

float fsec = 32025.89f, frac = 0;
int milliseconds = (int)(modf(fsec, &frac) * 1000);
int isec = (int)frac;
int hours = isec / 3600;
int minutes = (isec % 3600) / 60;
int seconds = isec % 60;
