RE: Double factorial [wp34s]
This doesn't use CNST. Only one more step than Dieter's:

Code:
LBL A
(-1)^x
DEC X
# pi
# 1/2
STOx Z
STOx Z
STOx Y
RCLx L
2^x
RCL L
x!
x
x<> Z
y^x
x
RTN

Corrupts all the (4 level) stack, but I'm planning to put it in XROM, so that will not be a problem.

C├ęsar - Information must flow.
