WebMar 19, 2011 · An IQmath application can be easily converted to use floating-point math instead of IQmath. MATH_TYPE selects the type of math to use; it can have one of two values: IQ_MATH - the default value, which performs all IQmath functions using fixed-point arithmetic in the IQmath library. WebNov 6, 2008 · Thanks, but I think IQmath may be a simpler porting of my code, but would not achieve the speedup of fundamentally changing my algorithm to use integers. I'm working on a project that is taking approximately 70ms to crunch data that takes 30ms to acquire. The FFT is a very small portion of the time
