Ruby Operators
Ruby has a builtin modern set of operators. Operators are a symbol which is used to perform different operations. For example, +, , /, *, etc.
Types of operators:
 Unary operator
 Airthmetic operator
 Bitwise operator
 Logical operator
 Ternary operator
 Assignment operator
 Comparison operator
 Range operator
Unary Operator
Unary operators expect a single operand to run on.
Operator 
Description 
! 
Boolean NOT 
~ 
Bitwise complement 
+ 
Unary plus 
Example
In file hello.rb, write the following code.
Output:
Airthmetic Operator
Airthmetic operators take numerical values as operands and return them in a single value.
Operator 
Description 
+ 
Adds values from both sides of the operator. 
 
Subtract values from both sides of the operator. 
/ 
Divide left side operand with right side operand. 
* 
Multiply values from both sides of the operator. 
** 
Right side operand becomes the exponent of left side operand. 
% 
Divide left side operand with right side operand returning remainder. 
Example
In file hello.rb, write the following code.
Output:
Bitwise Operator
Bitwise operators work on bits operands.
Operator 
Description 
& 
AND operator 
 
OR operator 
<< 
Left shift operator 
>>

Right shift operator 
^ 
XOR operator 
~ 
Complement operator 
Logical Operator
Logical operators work on bits operands.
Operator 
Description 
&& 
AND operator 
 
OR operator 
Ternary Operator
Ternary operators first check whether given conditions are true or false, then execute the condition.
Operator 
Description 
?: 
Conditional expression 
Example
In file hello.rb, write the following code.
Output:
Assignment Operator
Assignment operator assign a value to the operands.
Operator 
Description 
= 
Simple assignment operator 
+= 
Add assignment operator 
= 
subtract assignment operator 
*= 
Multiply assignment operator 
/= 
Divide assignment operator 
%= 
Modulus assignment operator 
**= 
Exponential assignment operator 
Comparison Operator
Comparison operators compare two operands.
Operator 
Description 
== 
Equal operator 
!= 
Not equal operator 
> 
left operand is greater than right operand

<

Right operand is greater than left operand 
>= 
Left operand is greater than or equal to right operand 
<= 
Right operand is greater than or equal to left operand 
<=> 
Combined comparison operator 
.eql? 
Checks for equality and type of the operands 
equal? 
Checks for the object ID 
Example
In file hello.rb, write the following code.
Output:
Range Operator
Range operators create a range of successive values consisting of a start, end and range of values in between.
The (..) creates a range including the last term and (...) creates a range excluding the last term.
For example, for the range of 1..5, output will range from 1 to 5.
and for the range of 1...5, output will range from 1 to 4.
Operator 
Description 
.. 
Range is inclusive of the last term 
... 
Range is exclusive of the last term
