Forums Feature Suggestions $calc support of factorials

I suggest that with $calc you support "factorials"

ex:
$calc(10!)
would return the same as
$calc(10*9*8*7*6*5*4*3*2*1)

As you can see it cuts down on the work you have to input to $calc.

I'm pretty sure most of us know what factorial is ;b
Bur can you tell a reason why to add it?
After all it easily enough to script it, and I can see much use for it
New additions are not bad, but I hope you realize that Khaled will not add every single requested feature, especialy things that will have no or very little use
for example I would die to see Dirac's delta function implemented

alias math::factorial { if ($1 == 0) return 1 | if ($1 > 35) return $null | var %total = 1, %cur = $1 | while (%cur > 1) { %total = %total * %cur | dec %cur } | return %total }

The max of 35 is cause $calc() is broken and can't do math on exponential numbers.
