fit :: Real a => Real b => Integral c => a > b > c Source #
fit a b
computes how many b
s are needed to fit a
, i.e.
\(\left\lceil\frac{a}{b}\right\rceil\).
For instance,
>>>
fit 7 3
3
>>>
fit 6 3
2
intFit :: Integral a => Integral b => a > b > a Source #
fit a b
computes how many b
s are needed to fit a
, i.e.
\(\left\lceil\frac{a}{b}\right\rceil\).
For instance,
>>>
intFit 7 3
3
>>>
intFit 6 3
2
nextPowerOfTwo :: Real a => Integral b => a > b Source #
nextPowerOfTwo a
computes the smallest power of two that is larger or
equal than a
.
intNextPowerOfTwo :: Int > Int Source #
nextPowerOfTwo a
computes the smallest power of two that is larger or
equal than a
.
:: PrimMonad m

Write a Word64
value into a Word32
aligned MutableByteArray
:: PrimMonad m  
=> MutableByteArray (PrimState m)  byte array 
> Int  index in terms of

Hash functions
Computes a Sip hash for a value that has an Storable
instance.
The first argument is a salt value that is used to derive the key for the hash computation.
Computes a 64 bit Fnv1a hash for a value that has an Storable
instance.
The first argument is use as a salt.
:: ByteArrayAccess a  
=> Int  Salt 
> a  Value that is hashes 
> Word64 
Computes a 64 bit Fnv1a hash for a value that is an instance of
ByteArrayAccess
.
The first argument is use as a salt.
:: ByteArrayAccess a  
=> Int  Salt 
> a  Value that is hashes 
> Word64 
Computes a Sip hash for a value that is an instance of
ByteArrayAccess
.
The first argument is a salt value that is used to derive the key for the hash computation.
