LOG

Returns the natural logarithm of an expression that represents a numerical value.
If ex = a then LOG(a) = x. The LOG function is defined only for positive values of a (that is, a > 0). It's undefined for all other values.

Format

LOG(x)

Argument

 
x
Any valid expression that evaluates to a real number.

Example

The following function returns the natural logarithm of the expression (1+TIME), where TIME is the current simulation time:
LOG(1+TIME)
