LOG edit
Syntax edit
naturalLog# = LOG(expr)
Description edit
Returns the natural logarithm of expr. The natural logarithm uses the transcendental number "e" as its base. LOG always returns a double-precision result.
LOG is the inverse of the EXP function. That is: LOG(EXP(x)) equals x.
Note:
To find the logarithm of expr for an arbitrary base n, use this formula:
theLog# = LOG(expr)/LOG(n)
