Re: [Help-gsl] long double gsl_sf_exp()

[Daniel J Farrell]

Hi everybody,

Thanks for that. Unfortunately I'm  programming on a mac which treats  
long double differently that other platforms. The way long double is  
defined gives more precision to the floating point number (more  
meaningful significant figures) but very little in the way of  
extending the range of numbers available.

I have found gmp (http://www.swox.com/gmp/) which should allow me to  
calculate the number I want.

Kind regards all.

Daniel.
