Purpose
Returns the logarithm of an arithmetic expression to the base 10.
Parameters
x is a floating-point value greater than zero.
Examples
LOG10(100.0) /* returns 2 */
Restrictions
A LOG10 operation on floating-point decimal data is actually performed using the floating-point binary operation. Thus, the range of the operands and the result of the operation are limited to the ranges for floating-point binary numbers.
Description
The LOG10 function returns the logarithm of x to the base 10. Note that LOG10(x) is the inverse of 10**x, that is, 10**LOG10(x) = x = LOG10(10**x).
The result has the same data type as x.
