Numeric.Natural

Description

The arbitrary-precision Natural number type.

Since: base-4.8.0.0

Synopsis

data Natural

Documentation

data Natural Source #

Type representing arbitrary-precision non-negative integers.

>>> 2^100 :: Natural
1267650600228229401496703205376

Operations whose result would be negative throw (Underflow :: ArithException),

>>> -1 :: Natural
*** Exception: arithmetic underflow
