factor
exp1
(
expression )
Factor and expression yield integer
s, number
s, or complex
es.
put the exp1 of 2 -- yields 6.389056
The exp1
function returns 1 less than the mathematical exponential of its argument. That is, it returns:
(
euler
^number)-1
The exp1
function is faster and more accurate than using the above formula.
If the argument is an integer
or a number
, a number
is returned. If the argument is a complex
, a complex
is returned.
