Function:
expt x yThis function returns x raised to power y . If both
arguments are integers and y is positive, the result is an
integer; in this case, overflow causes truncation, so watch out.
If x is a finite negative number and y is a finite
non-integer, expt returns a NaN.

GNU Emacs Lisp Reference Manual: Math Functionsto the power
arg .
Function: log arg &optional base This function returns the logarithm of arg , with base
base . If you don’t specify base , the natural base
e is used. If arg or base is negative, log
returns a NaN.
<span>Function: expt x y This function returns x raised to power y . If both
arguments are integers and y is positive, the result is an
integer; in this case, overflow causes truncation, so watch out.
If x is a finite negative number and y is a finite
non-integer, expt returns a NaN.
Function: sqrt arg This returns the square root of arg . If arg is finite
and less than zero, sqrt returns a NaN.
