divModInteger :: Integer -> Integer -> (# Integer, Integer #) Source
Used to implement divMod for the Integral typeclass. This gives a tuple equivalent to
(div x y, mod x y)
>>> divModInteger 10 2 (5,0)
>>> divMod 10 2 (5,0)
divInteger :: Integer -> Integer -> Integer Source
Used to implement div for the Integral typeclass. This performs integer division on its two parameters, truncated towards negative infinity.
>>> 10 `divInteger` 2 5
>>> 10 `div` 2
modInteger :: Integer -> Integer -> Integer Source
Used to implement mod for the Integral typeclass. This performs the modulo operation, satisfying
((x `div` y) * y) + (x `mod` y) == x
>>> 7 `modInteger` 3 1
>>> 7 `mod` 3 1
quotRemInteger :: Integer -> Integer -> (# Integer, Integer #) Source

(quot x y, mod x y)
>>> quotRemInteger 10 2 (5,0)
>>> quotRem 10 2 (5,0)
quotInteger :: Integer -> Integer -> Integer Source
Used to implement quot for the Integral typeclass. This performs integer division on its two parameters, truncated towards zero.
>>> quotInteger 10 2 5
>>> quot 10 2 5
remInteger :: Integer -> Integer -> Integer Source
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
>>> remInteger 3 2 1
>>> rem 3 2 1
eqInteger :: Integer -> Integer -> Bool Source
Used to implement (==) for the Eq typeclass. Outputs True if two integers are equal to each other.
>>> 6 `eqInteger` 6 True
>>> 6 == 6 True
neqInteger :: Integer -> Integer -> Bool Source
Used to implement (/=) for the Eq typeclass. Outputs True if two integers are not equal to each other.
>>> 6 `neqInteger` 7 True
>>> 6 /= 7 True
leInteger :: Integer -> Integer -> Bool Source
Used to implement (<=) for the Ord typeclass. Outputs True if the first argument is less than or equal to the second.
>>> 3 `leInteger` 5 True
>>> 3 <= 5 True
gtInteger :: Integer -> Integer -> Bool Source
Used to implement (>) for the Ord typeclass. Outputs True if the first argument is greater than the second.
>>> 5 `gtInteger` 3 True
>>> 5 > 3 True
ltInteger :: Integer -> Integer -> Bool Source
Used to implement (<) for the Ord typeclass. Outputs True if the first argument is less than the second.
>>> 3 `ltInteger` 5 True
>>> 3 < 5 True
geInteger :: Integer -> Integer -> Bool Source
Used to implement (>=) for the Ord typeclass. Outputs True if the first argument is greater than or equal to the second.
>>> 5 `geInteger` 3 True
>>> 5 >= 3 True
compareInteger :: Integer -> Integer -> Ordering Source
Used to implement compare for the Integral typeclass. This takes two integers, and outputs whether the first is less than, equal to, or greater than the second.
>>> compareInteger 2 10 LT
>>> compare 2 10 LT
Int#-boolean valued versions of comparison predicatesThese operations return 0# and 1# instead of False and True respectively. See PrimBool wiki-page for more details
