Using Infinity in Calculations (DSP Module)
There are inherent differences between digital signal processors (DSPs) and general purpose processors, such as the processors in desktop PCs. Digital signal processors (DSPs) manage positive and negative infinity different than PCs.
On PCs, any operation with infinity generally returns either infinity or a domain error.
On DSPs, infinity is the largest positive value, and negative infinity is the largest possible negative value. However, if you perform mathematical operations with infinity, the DSP treats the value as a finite value, performs the operation, and returns the value. For example, infinity minus one is a known finite value that is very close to infinity, but not exactly infinity.
