The element <numberOperator> is an operator between two number (integer or real data type) expressions in the Process DM. The operator evaluates the two element <expression>s based on the attribute "numberOperation" with following definitions– "divide" – Returns a number of the first number divided by the second number. • "equal" – Returns "true" if the numbers are the same otherwise returns "false". • "exponent" – Returns a number of the first number raised to the power of the second number. • "greaterThan" – Returns "true" if the first number is greater than the second number otherwise returns "false". • "greaterThanOrEqual" – Returns "true" if the first number is greater than or equal to the second number otherwise returns "false". • "integerDivide" – Returns the integer number of the first number divided by the second number, truncated to an integer data type. • "lessThan" – Returns ""true" if the first number is less than the second number otherwise "false". • "lessThanOrEqual" – Returns "true" if the first number is less than or equal to the second number otherwise returns "false". • "minus" – Return the number of the first number minus the second number. • "modulus" – Returns the integer number remainder after the first number is integer-divided by the second number. • "notEqual" – Returns "true" if the values are different otherwise returns "false". • "plus" – Returns the number of the first number plus the second number. • "times" – Returns the number of the first number multiplied by the second number.
