What is 'correct' here, mathematically correct, or something else?
Mathematically you're right of course. But in mathematica & co, you'll
also get a much nicer view on formula's than in PHP...

I agree. Do you suggest here to hold these two, until some kind of
advanced-math-extension will be added?
Some other thing, the M_* constants. I always wondered why for example
M_2_SQRTPI (2/sqrt(PI)) was in PHP. IMO, there are only one or two essential
constants to be in the core: PI (of course), and (possibly) the
What about adding PI and, possibly, EULER as constant (without the M_), and
deprecating those M_ constants? Or at least promote them to the
