Function Documentation

float expsp ( float  a  ) 

Description:
The expsp function returns the exponential function of a real floating-point argument a. The return value is the number e raised to power a. If the magnitude of a is too large, the maximum single-precision floating-point number (3.402823e+38 = 2^128) is returned.
Parameters:
[in] a = Input float
Returns:
Resultant float
Special Cases:
  • If a > +88.7228, then the return value is 3.402823e+38 = 2^128 (maximum single-precision floating-point number).
  • If a < -87.3365, then the return value is 0.0.
  • If a < -256, then the return value may be random for Asm implementation only.

Implementation Notes:
  • The code supports both big and little endian modes.
