The goal is the find the magnitude of a number (ie. the exponent in scientific notation)
ex:
135 returns 2 (1.35e2)
.001 returns -3 (1e-3)

"Magnitude" I think is not the correct term, more like "exponent" as in "mantissa and exponent" like in here.

For the cost of one more byte, this works for all real numbers (assuming the argument is stored in Ans): [whiteout]int(log(abs(Ans[/whiteout]
(from here)
