Fast Factorial

Description:This program calculates the exact factorial of an integer. While the HP 49g+ has this built in, this program runs roughly forty times faster. 1000! takes FFAC about .35 seconds to calculate. The built in routine takes 27.5 seconds. FFAC runs natively on the ARM CPU. This is the first such user-made program for the 49g+. This program shows what the 49g+ is capable of when running native code. For the 49g+ only!
