Returns log to base 10 of an expression that represents a numerical value.
If 10y = x, then LOG10(x) = y. The LOG10 function is defined only for positive values of x (that is, x > 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 example illustrates the use of the LOG10 function:
Function | LOG10(42) |
Result | 1.6 |
