Operators in Ruby

Operators in Ruby

Ruby supports a wide variety of operators

  • Unary Operators
  • Arithmetic Operators
  • Bitwise Operators
  • Logical Operator
  • Ternary Operator
  • Comparison Operator
  • Range Operator

Let us look into each type of operator in detail

Arithmetic Operator

These operators perform necessary arithmetic operations on the operands. These computations include all the operations that are defined in the table below.

Let x and y be two operands

Operator Operation Expression Description
+ Addition a+b Returns sum of a & b
- Subtraction a-b Returns difference of a&b
/ Division a/b Returns quotient of a&b
* Multiplication a*b Returns product of a&b
** Exponent a**b Returns a to the power b
% Modulus x%y Returns remainder of a&b

Comparison Operators

Comparison operators unlike arithmetic operators only compare two values and return true or false as the result

Operator Operation Expression x=y x>y x<y<y< th=""></y<>
== Equal to x == y True False False
!= Not Equal to x != y False True True
<= Less than equal to x <= y True False True
>= Greater than Equal to x >= y True True False
< Less than x < y False False True
> Greater than x > y False True False
<==> Combined Comparision x <==> y 0 1 -1

Bitwise Operator

Bitwise operators perform operations on a bit level. After converting the value into binary form, the bitwise operators perform operations on corresponding bits of the operands.

Operator Operation  Expression   Description
& Bitwise AND  a&b Returns 1 when both corresponding bits are 1
| Bitwise OR  a|b Returns 1 when either corresponding bits are 1
^ Bitwise XOR  a^b Returns 0 only when both bits are 1
~ Compliment  ~a Flips all the bits in the binary form of the operand
<< Left Shift  a<<b< td=""></b<> shifts all the bits to the left by one position*
>> Right Shift  a>>b shifts all the bits to the right by one position*

*In Left/Right shifts the leftmost/rightmost bit is discarded and 0 is inserted towards the other end.

Ternary Operator

Operator Description
?: Conditional expression
