Need help with symbols


#1

Can someone ecplain to me what each of these mean please?

=>
=<
<=

=

Thanks


#2
=>
=<

These two operators don't exist in Ruby as far as I know.

<=
>=

These two operators mean respectively "lesser than or equal to" and "greater than or equal to".

=

This is the assignation operator, it's used to assign a value to something, for example:

my_variable = 42

#3

<= operator is used for less than (<) or equal to (=)
3<=4 (true)
3<=3 (true)

= operator is used for greater than (>) or equal to (=)
4>=3 (true)
4>=4 (true)
