NSNumber and long double

[Daniel J Farrell]

Hello everyone,

Can NSNumber containing long double data-type? The docs say in order  
to return a number as a long double, use:

- (long)longValue Returns the receiver's value as a long double  
precision floating point value.

In the example below I am using +numberWithLong:, however when  
returned this prints out a NaN.

  long double num = 1e300;
  NSNumber *d = [NSNumber numberWithLong:num];
  printf("\n\n%Le",[d longValue]);

  //output nan

How do I use long doubles with GNUstep?

Cheers,

Dan.
