Error function erf(x) implementation in C.

Hi, does anyone knows where I can find a good and simple implementation
of erf(x) for C or C++?, because I need to convert it to Verilog A....

Hi

you should consider implementing an approximation of the function via
polynomial evaluation. This involves the computation of
fixed-/floating-point coefficients for the polynomial either the Taylor
or the Remez (minimax) way.

One good source for approximations of transcendental functions is
