Operators

• Operators are special characters that perform certain functions
• Arithmetic operators take two values and perform a maths function on them
• The exponentiation operator is used to raise a number to a power
• The DIV operator returns the whole number part of a division , and the MOD operator gives the remainder
• Dividing integers might behave oddly in some programming languages (e.g. 5 / 2 may give 2 instead of 2.5), so using DIV and MOD can avoid these issues
• The typical operator for the Addition function is +
• The typical operator for the Subtraction function is -
• The typical operator for the Multiplication function is *
• The typical operator for the Division function is /
• The typical operator for the Exponentiation function is ^ (or **)
• The typical operator for the Quotient function is DIV
• The typical operator for the Remainder(modulus) function is MOD (or %)
• When using operators, computers follow the rule of BODMAS - To make sure your code is doing what you want it to , you should use brackets
• The assignment operator , = , is used to assign values to constants or variables
• Comparison operators compare the expression on their left hand side to the expression on their right hand side , and produce a Boolean value (true or false)
• The comparison operator == means?

  Is equal to
• The comparison operator != or <> means?

  Is not equal to
• The comparison operator < means?

  Is less than
• The comparison operator > means?

  Is greater than
• The comparison operator <= means?

  Is less than or equal to
• The comparison operator >= means?

  Is greater than or equal to
• A common mistake is to get the assignment operator " = " and the comparison operator " == " mixed up - You'll know you've used them incorrectly because your code won't behave as intended
