* The addition of rint() (by Peter Schneider-Kamp; I forgot to mentionGuido van Rossum2000-05-111-0/+4
| | | | | | that before) in the previous patch has one problem; rint() is not in the C math library on all platforms (e.g. not for VC++). Make it conditional on HAVE_RINT.
* Added math.rint() -- round according to current IEEE754 modeGuido van Rossum2000-05-111-0/+3

* Trent Mick:Guido van Rossum2000-05-081-4/+4
| | | | | | | | | | | | | Fix overflow bug in ldexp(x, exp). The 'exp' argument maps to a C int for the math library call [double ldexp(double, int)], however the 'd' PyArg_ParseTuple formatter was used to yield a double, which was subsequently cast to an int. This could overflow. [GvR: mysteriously, on Solaris 2.7, ldexp(1, 2147483647) returns Inf while ldexp(1, 2147483646) raises OverflowError; this seems a bug in the math library (it also takes a real long time to compute the Inf outcome). Does this point to a bug in the CHECK() macro? It should have discovered that the result was outside the HUGE_VAL range.]

* Changes for Lee Busby's SIGFPE patch set.Guido van Rossum1997-02-141-0/+6
| | | | | Two new modules fpectl and fpetest. Surround various and sundry f.p. operations with PyFPE_*_PROTECT macros.
* Removed references to getdoublearg and get2doublearg rename macros andRoger E. Masse1996-12-181-8/+5
| | | | substituted the appropriate PyArg_Parse calls. Retested. All appears well.

* Don't make an exception for NeXT (BBUM says it's no longer needed).Guido van Rossum1996-07-301-1/+1
| | | | | (But hypot() should really be defined in a separate file, triggered by configure.)
