  1. badSafeIndex :: Int -> Int -> Int

    base GHC.Arr

    Used to throw exceptions in array bounds-checking functions. ⚠ This function throws SomeException in all cases.

    Examples

    >>> badSafeIndex 2 5
*** Exception: Error in array index; 2 not in range [0..5)

  2. quotInt :: Int -> Int -> Int

    base GHC.Base

    Used to implement quot for the Integral typeclass. This performs integer division on its two parameters, truncated towards zero.

    Example

    >>> quotInt 10 2
5

    >>> quot 10 2
5

  3. remInt :: Int -> Int -> Int

    base GHC.Base

    Used to implement rem for the Integral typeclass. This gives the remainder after integer division of its two parameters, satisfying 

    ((x `quot` y) * y) + (x `rem` y) == x

    Example

    >>> remInt 3 2
1

    >>> rem 3 2
1

  4. divInt :: Int -> Int -> Int

    base GHC.Base

    Used to implement div for the Integral typeclass. This performs integer division on its two parameters, truncated towards negative infinity.

    Example

    >>> 10 `divInt` 2
5

    >>> 10 `div` 2
5

  5. modInt :: Int -> Int -> Int

    base GHC.Base

    Used to implement mod for the Integral typeclass. This performs the modulo operation, satisfying 

    ((x `div` y) * y) + (x `mod` y) == x

    Example

    >>> 7 `modInt` 3
1

    >>> 7 `mod` 3
1

  6. clamp :: Int -> Int -> Int

    base GHC.Float

    Used to prevent exponent over/underflow when encoding floating point numbers. This is also the same as 

    \(x,y) -> max (-x) (min x y)

    Example

    >>> clamp (-10) 5
10

  7. mul :: Int -> Int -> Int

    text Data.Text.Internal

    Checked multiplication. Calls error if the result would overflow.

  8. gcdInt :: Int -> Int -> Int

    ghc-bignum GHC.Num.BigNat

    Greatest common divisor between two Int Warning: result may become negative if (at least) one argument is minBound

  9. roundUp :: Int -> Int -> Int

    storable-record Foreign.Storable.FixedArray

    No documentation available.

  10. stepStartAdjust :: Int -> Int -> Int

    massiv Data.Massiv.Core.Index

    Helper for adjusting stride of a chunk
