[Bug-gsl] Re: Bug-gsl Digest, Vol 99, Issue 1

[James Ward]

Mathematically, they're equivalent, but what's the point of defining z
at all? It's only used in that one sin. It looks like the author:

else if(x > -0.5/(GSL_DBL_EPSILON*M_PI))

is trying to avoid some kind of overflow/underflow. I'm guessing:

double s  = sin(M_PI*z);

is correct ... but I'm no expert.

Best wishes,

Jim Ward
