ASA066
The Standard Normal Cumulative Density Function

ASA066 is a FORTRAN77 library which computes the cumulative density function of the standard normal distribution, by David Hill.

ASA066 is Applied Statistics Algorithm 66. Source code for many Applied Statistics Algorithms is available through STATLIB.

Languages:

ASA066 is available in a C version and a C++ version and a FORTRAN77 version and a FORTRAN90 version and a MATLAB version.
