VM Mathematical Functions
This section describes VM functions that compute values of mathematical functions on real and complex vector arguments.
Each function is introduced by its short name, a brief description of its purpose, and the calling sequence for each type of data, as well as a description of the input/output arguments.
The input range of parameters is equal to the mathematical range of the input data type, unless the function description specifies input threshold values, which mark off the precision overflow, as follows:
- FLT_MAXdenotes the maximum number representable in single precision real data type
- DBL_MAXdenotes the maximum number representable in double precision real data type
