[1 of 1] Compiling Data.FixedPoint ( Data/FixedPoint.lhs, dist/build/Data/FixedPoint.o )
Data/FixedPoint.lhs:596:30: error:
• Could not deduce (Num a) arising from the literal ‘0’
from the context: (Bits a, Ord a)
bound by the instance declaration at Data/FixedPoint.lhs:590:12-45
Possible fix:
add (Num a) to the context of the instance declaration
• In the second argument of ‘(<)’, namely ‘0’
In the expression: a < 0
In the first argument of ‘(.)’, namely
‘(if a < 0 then
\ x
-> foldl setBit x [bitSize a - 1, bitSize a - 2 .. bitSize a - i]
else
id)’
Data/FixedPoint.lhs:633:28: error:
• Could not deduce (Num a) arising from a use of ‘fromIntegral’
from the context: (Bounded a, Ord a, Bits a)
bound by the instance declaration at Data/FixedPoint.lhs:632:12-59
Possible fix:
add (Num a) to the context of the instance declaration
• In the expression: fromIntegral (negate (2 ^ (bitSize r - 1)))
In an equation for ‘r’:
r = fromIntegral (negate (2 ^ (bitSize r - 1)))
In the expression:
let r = fromIntegral (negate (2 ^ (bitSize r - 1))) in r
