Operators

Arithmetic Operators

Basic math operations can be applied to integer and floating point values:

• + addition
• - subtraction
• * multiplication
• / division
• % modulo (yields the remainder)

a = 30;
b = 20;

puts a + b
# Output: 50

puts a - b
# Output: 10

puts a * b
# Output: 600
puts a / b
# Output: 1.5
puts a % b
# Output: 10

Comparison Operators

Comparison operators can be used to compare two values:

• > greater than
• < less than
• >= greater than or equal to
• <= less than or equal to
• == equal to
• != not equal to

The result of a comparison is a boolean value true or false:

a = 5;
b = 3;

puts a > b;
# Output: true
