Arithmetic Operators

The following table lists the operators that can be used in a method to perform mathematical calculations:

PBL Style	Java Style	Visual Basic Style	Description
`+`	`+`	`+`	Addition
`-`	`-`	`-`	Subtraction
`*`	`*`	`*`	Multiplication
`/`	`/`	`/`	Division
`rem`	`%`	`Mod`	Modulo (Remainder)

Order of Precedence

When multiple operators are used within an expression, the following order of precedence is followed:

operators within parentheses are evaluated first
multiplication, division, and modulo are evaluated from left to right
addition and subtraction are evaluated from left to right

Using Variables with Arithmetic Operators

Variables of Int, Decimal, Real, Time, and Interval types may be used as operands of arithmetic operators. The result of a given expression is based on the following rules:

If any of the operands is Real, the result is Real
If any of the operands is Decimal and none are Real, the result is Decimal with sufficient places to hold the operation's sum, difference, multiplication, or remainder
If both operands are Integer, the result is Integer
Monadic '-' (change of sign) and '+' identity are supported
The result always has at least the precision of the operand with the highest precision in the expression
