public class AbsExpressionStateObject extends AbstractSingleEncapsulatedExpressionStateObject
ABS
function removes the minus sign from a specified argument and returns
the absolute value, which is always a positive number or zero.
This is one of the JPQL arithmetic functions. The ABS
function takes a
numeric argument and returns a number (integer, float, or double) of the same type as the
argument to the function.
