Arithmetic Operators

Use arithmetic operators to perform mathematical calculations on numeric data.

The following table lists the arithmetic operators in order of precedence in the transformation language:

Operator	Meaning
+, -	Unary plus and minus. Unary plus indicates a positive value. Unary minus indicates a negative value.
*, /, %	Multiplication, division, modulus. A modulus is the remainder after dividing two integers. For example, 13 % 2 = 1 because 13 divided by 2 equals 6 with a remainder of 1.
+, -	Addition, subtraction. The addition operator (+) does not concatenate strings. To concatenate strings, use the string operator \|\|. To perform arithmetic on date values, use the date functions.

If you perform arithmetic on a null value, the function returns NULL.

When you use arithmetic operators in an expression, all of the operands in the expression must be numeric. For example, the expression

1 + '1'

is not valid because it adds an integer to a string. The expression

1.23 + 4 / 2

is valid because all of the operands are numeric.

The transformation language provides built-in date functions that let you perform arithmetic on date/time values.
