Returns true if self is numerically less than or equal to other:

Example

2.0 <= 3              # => true
2.0 <= 3.0            # => true
2.0 <= Rational(3, 1) # => true
2.0 <= 2.0            # => true
2.0 <= 1.0            # => false

Float::NAN <= Float::NAN returns an implementation-dependent value.
