Exponential Functions

MathLib provides six exponential functions:

$exp(x)$	The base e or natural exponential $e$x .
$exp2(x)$	The base 2 exponential $2$x .
$expm1(x)$	The base e exponential minus 1.
$ldexp(x,n)$	Returns $x\times 2$n (equivalent to scalb).
$pow(x,y)$	Returns $x$y .
$scalb(x,n)$	Returns $x\times 2$n .
