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.
