Re: Trying to access a function that was in fp.h - nextafterd

Thanks, for the help. It now works. Changed nextafterd to nextafter .

As someone who has to write documentation for my programs, could you pass a note onto the Apple documentation team that the function has changed.

Cheers Peter.

Hi,

Working on some code, that uses the function nextafterd that was part of fp.h on codewarrior.

I am now getting a compiler error "not declared in this scope" on this function in XCode 2.1 on a G5.

After trying many different includes types, then reading all the documentation, sample codes and googling, still no luck.

The most strange part is the function nextafterf works.

So has anyone else come across this problem?
Is it a problem with GCC 4 and doubles?

Any ideas,
Cheers Peter.


Hi Peter,

Try nextafter instead.  The (C99) standard overloads are:

double nextafter(double x, double y);
float nextafterf(float x, float y);
long double nextafterl(long double x, long double y);
