What all this means is that there is a "core" calculation, plus some extra tricks that may or may not come into play depending on the range of x. Figure 1 shows the mean time required to calculate Math.exp(x) for a range of x values from -1 to +2. ...

By the restriction of a Laurent polynomial f in a subspace S we mean the S-fiber ∑u∈Supp(f)∩Sfuxu, and we denote it by f↾S. Thus the restriction is the sum of those monomials of f that lie in S. We are actually interested in S-fibers of f in all “slices” parallel to...

It was ambiguous: ('e' to the power of num) minus one, or 'e' to the power of (num minus one) I mean: pow(2, 3) - 1 !== pow(2, 3 -1)
