public final class ModExpression
The modulo operation finds the remainder of division of one number by another.
It takes two integer arguments and returns an integer.
JPA 1.0, 2.0:
expression ::= MOD(simple_arithmetic_expression, simple_arithmetic_expression)
JPA 2.1:
expression ::= MOD(arithmetic_expression, arithmetic_expression)
