Numeric.Data.ModN.Internal

Description

Provides the ModN type for modular arithmetic.

Since: 0.1

Synopsis

Type

newtype ModN (n :: Nat) a Source #

Newtype wrapper that represents \( \mathbb{Z}/n\mathbb{Z} \). ModN is a Ring i.e. supports addition, subtraction, and multiplication.

When constructing a ModN n a we must verify that the type a is large enough to accommodate n, hence the possible failure.

Examples

Expand
>>> import Data.Text.Display (display)
>>> display $ unsafeModN @7 10
"3 (mod 7)"

Since: 0.1

Constructors

UnsafeModN a 

Bundled Patterns

pattern MkModN :: a -> ModN n a

Bidirectional pattern synonym for ModN. Construction will apply modular reduction to the parameter.

Constructor for ModN.

Examples

Expand
>>> mkModN @5 7
Right (MkModN 2 (mod 5))

>>> mkModN @10 7
Right (MkModN 7 (mod 10))

>>> mkModN @128 (9 :: Int8)
Left "Type 'Int8' has a maximum size of 127. This is not large enough to safely implement mod 128."

unsafeModN :: forall (n :: Nat) a. (FromInteger a, HasCallStack, KnownNat n, MaybeUpperBounded a, MEuclidean a, ToInteger a, Typeable a) => a -> ModN n a Source #

Variant of mkModN that throws an error when type a is not large enough to fit n.

WARNING: Partial

Examples

Expand
>>> unsafeModN @7 12
MkModN 5 (mod 7)

Since: 0.1

reallyUnsafeModN :: forall (n :: Nat) a. (FromInteger a, KnownNat n, MEuclidean a) => a -> ModN n a Source #

This function reduces the argument modulo p but does not check that n fits within a. Note that correct behavior requires this, so this is dangerous. This is intended only for when we absolutely know n fits in a and the check is undesirable for performance reasons. Exercise extreme caution.
