double exp10dp_c (double a)

Function Documentation

double exp10dp ( double  a  ) 

Description:
The exp10dp function returns the exponential function of a real floating-point argument a. The return value is the number 10 raised to the 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 | < 3.34e-17, then the return value is 1.0 for small arguments.
  • If a < -307.6527, then the return value is 0.0.
  • If a > +308.2547, then the return value is 1.797693e+308 = 2^1024 (maximum double-precision floating-point number).

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