exp - exponential function
SYNOPSIS
exp(x [,eps])
TYPES
x real or complex
eps nonzero real, defaults to epsilon()
return real or complex
DESCRIPTION
Approximate the exponential function of x by a multiple of epsilon,
the error having absolute value less than 0.75 * eps.
If n is a positive integer, exp(x, 10^-n) will usually be
correct to the n-th decimal place, which, for large positive x
will give many significant figures.
