Exponentiation (**)
The ** operator
calculates an exponentiation.
Syntax

Usage
The ** operator
returns a value calculated by raising the left-hand operand

If the right operand is a number with a decimal part, it is rounded to a whole integer before computing the exponentiation.
If one of the operands is NULL, the arithmetic expression evaluates to
NULL.
