The expdp 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 double-precision floating-point number (1.797693e+308 = 2^1024) is returned.
Parameters:
[in]
a
= Input double
Returns:
Resultant double
Special Cases:
If | a | < 7.69e-17, then the return value is 1.0 for small arguments.
If a < -708.3964, then the return value is 0.0.
If a > +709.7827, then the return value is 1.797693e+308 = 2^1024 (maximum double-precision floating-point number).
