exp(511)

Hmm. My data point:

exp(101);

(1) Result: 73070599793680668906492145854235224565612544.000000

exp(102);

Segmentation fault

Pike 7.4.13 on Linux 2.4.17 i686, glibc-2.3.1

The segfault is due to sprintf("%O",...); write("%e", exp(x)) is OK up to x=710 (at which point it turns "inf" of course).

Aah, nearly forgot: --with-long-double-precision.

I'm happy as long as it doesn't segfault. It probably has a problem because I'm using double precision (up to around e^180 is ok).

I added tests to check that it returns strings for medium (e^200) and large (e^65536) for all five float formats.
