fromNumber :: (Ord a, C a) => a -> T a Source #

Convert a number to a non-negative number. If a negative number is given, an error is raised.

fromNumberMsg Source #

Arguments

:: (Ord a, C a)
=> String	name of the calling function to be used in the error message
-> a
-> T a

fromNumberClip :: (Ord a, C a) => a -> T a Source #

Convert a number to a non-negative number. A negative number will be replaced by zero. Use this function with care since it may hide bugs.

fromNumberUnsafe :: a -> T a #

Wrap a number into a non-negative number without doing checks. This routine exists entirely for efficiency reasons and must be used only in cases where you are absolutely sure, that the input number is non-negative.

toNumber :: T a -> a #

type Int = T Int #

type Integer = T Integer #

type Float = T Float #

type Double = T Double #

type Ratio a = T (T a) Source #

type Rational = T Rational Source #
