Details:
I run the gsl_airy_deriv function at input -5.643803094122288e+102, the result
is
1.23773099046e+25. But the results should be <0.
So I used the mpmath airyai(t,1), I got the result:-2.35733848063182e+25
I want to know the input is in the domain of gsl_airy_deriv?
Why the results so different?
