Returns log to base 10 of an expression that represents a numerical value.
If 10x = a, then LOG10(a) = x. The LOG10 function is defined only for positive values of a (that is, a > 0). It is undefined for all other values.
Format
LOG10(x)
Argument
x | Any valid expression that evaluates to a real number. |
Example
The following function returns the base 10 logarithm of the expression:
LOG10(1+VM(marker_21, marker_31))
