Maintenance Ruby 3.3 gets fixes, but no new features. Switch to Ruby 4.0 →

instance method

Integer#<=

self <= real → true or false

Returns true if the value of self is less than or equal to that of other:

Example
1 <= 0              # => false
1 <= 1              # => true
1 <= 2              # => true
1 <= 0.5            # => false
1 <= Rational(1, 2) # => false

Raises an exception if the comparison cannot be made.
