Exact factorial/gamma values for half-integers
is it possible to return exact values of (n+1/2)! and ?(n+1/2) for n is an integer?

Sage already supports this (at least as of 4.8):
sage: factorial(3/2)
3/4*sqrt(pi)
sage: gamma(5/2)
3/4*sqrt(pi)
Ah. It doesn't for decimal inputs, like 1.5, but it does for 3/2. Thanks
If you give a numeric input, it'll give you a numeric output. If you want an exact output, give it an exact input.
