Arithmetical operations

Syntax

expression1 + expression2
or
expression1 - expression2
or
expression1 * expression2
or
expression1 / expression2
or
expression1 % expression2

where:

• expression: an MQL expression that evaluates to a number value.

Description

These arithmetical operators are the same as in usual languages:

• Addition: +
• Subtraction: -
• Multiplication: *
• Division: /
• Modulus (remainder): %

The operators will work with numbers values only.

There is an exception to the above rule. The + operator, is used to concatenate strings as well. If on one side of + is a string and on the other side of + is a numerical value, then it will convert the numerical value to string (using the format appropriate for language of the page) and then use the + as string concatenation operator.

Examples

a + b

a * b
