(8.D.2.7) MathException
Overview
Eliminates NaN and Inf from data
Discussion
This module detects NaN and Inf values in floating-point data and sets them to replacementValue. The module also keeps track of how many of each type of exception is detected. .infCount contains the number of Inf values seen (both positive and negative). .nanCount contains the number of NaN values see.
The module is useful for debugging mathematical errors such as divide by zero.
Type Definition
