NAME

log - natural logarithm function

SYNOPSIS

v = log(NumExpr)

DESCRIPTION

Log returns the natural logarithm of its argument; i.e., the power to which e must be raised in order to obtain NumExpr, where e is the transcendental number whose value is approximately 2.71828. 

NumExpr may be any numeric expression whose value is greater than zero. 

EXAMPLE

The program
	print log(34/9)
produces
	1.329135919230697

SEE ALSO

exp

DIAGNOSTICS

If the value of NumExpr is zero or negative, an "Illegal function call" error occurs.
