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.

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.
