NAME
    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.

    > print exp(2, 1e-5), exp(2,1e-10), exp(2, 1e-15), exp(2, 1e-20)
