Floating point with CW for Coldfire v4.0.2.4 and MCF5272

Hello, I'm using Codewarrior for Coldfire v4.0.2.4, targeting a MCF5272. My project is set to perform software floating point operations. I have a function that returns a float as follows:

float GetProcessorPeriodF() {
  float fPeriod=0;
  fPeriod = (float) 1 / 48;
  fPeriod *= 1000;
  return (float) fPeriod;
}

The function produces the right float number (20.83) but when it returns, the float variable that gets the value looks like this:
(fTest = GetProcessorPeriodF() fTest = 1.101442e+09

I don't know what's going on. I'll appreciate your help. Thank you, Martin


J2MEJediMaster added CW version and MCU type to header, cleaned up code
