I just repeated this test, on the following 4 platforms:
1) SunOS fsui02 5.6 Generic_105181-21 sun4u sparc SUNW,Ultra-Enterprise
cc: WorkShop Compilers 4.2 30 Oct 1996 C 4.2
2) OSF1 V4.0 878 alpha
DEC C V5.6-079 on Digital UNIX V4.0 (Rev. 878)
3) IRIX64 6.5 07151432 IP27
MIPSpro Compilers: Version 7.2.1
4) Linux 2.2.16 #31 SMP Thu Jun 29 14:51:26 CDT 2000 i686
gcc version 2.95.2 19991024 (release)
On all of the above systems, math.exp(-999) returns 0.0, math.sqrt(-1)
raises an exception, and test_math.py completes successfully.
Testing-ly (not to be confused with testily) yr's,
