Many thanks to the numerous people who contributed to this update.
Thanks, guys! This is a pretty awesome release. :) I especially like
that opPow made it in, and also the changes to std.math look very
useful.
I have one question regarding the latter: What exactly is supposed to
happen when I run the example in the FloatingPointControl
documentation? Is the program supposed to crash with some informative
error message, or do I have to do something to catch the exception?
Currently, nothing out of the ordinary happens when I run it on my
computer -- y just becomes NaN when x is NaN.
Aargh, the example's wrong. DMD optimizes the assignment into a blit.
Try setting y = x*2.
I take that back. The example is correct. This code...
-----
import std.math;
void main()
{
real x;
FloatingPointControl fpctrl;
fpctrl.enableExceptions(FloatingPointControl.severeExceptions);
double y = x*3.0;
}
----
results in:
object.Error: Invalid Floating Point Operation
However, it seems that the compiler is no longer creating variables of
type double and float as signalling NaNs. That's a bug.
OK, thanks for explaining. :)
