Documentation
data CReal (n :: Nat) Source #
The type CReal represents a fast binary Cauchy sequence. This is a Cauchy sequence with the invariant that the pth element divided by 2^p will be within 2^p of the true value. Internally this sequence is represented as a function from Ints to Integers.
Instances
KnownNat n => Eq (CReal n) Source #  Values of type

Floating (CReal n) Source #  
Fractional (CReal n) Source #  Taking the reciprocal of zero will not terminate 
Num (CReal n) Source # 
This is a little bit of a fudge, but it's probably better than failing to terminate when trying to find the sign of zero. The class still respects the abssignum law though.

KnownNat n => Ord (CReal n) Source #  Like equality values of type 
KnownNat n => Read (CReal n) Source #  The instance of Read will read an optionally signed number expressed in decimal scientific notation
