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.

to the power arg . Function: log arg &optional base This function returns the logarithm of arg , with base base . If you donâ€™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.
