constructor
A new instance of PNumericType.
- #instance?(o, guard = nil) ⇒ Boolean
-
#intersect?(o) ⇒ Boolean
Checks if this numeric range intersects with another.
-
#numeric_from ⇒ Float, Integer
Same as #from but will return ‘-Float::Infinity` instead of `nil` if no lower bound is set.
-
#numeric_to ⇒ Float, Integer
Same as #to but will return ‘Float::Infinity` instead of `nil` if no lower bound is set.
-
#to ⇒ Float, Integer
Returns the upper bound of the numeric range or ‘nil` if no upper bound is set.
- #unbounded? ⇒ Boolean
