0.5.0.0

  • Add NotZero data type for non-zero integers (positive or negative) with HasNotZero, AsNotZero classes, SumNotZero, MaxNotZero, MinNotZero newtype wrappers, and functions: positiveNotZero, negativeNotZero, notZeroPositive, notZeroInteger, isPositive, isNegative, negateNZ, absoluteNZ, signumNZ, plusNZ, multiplyNZ, notZeroOr
  • Add AsPositive NotZero instance
  • Add ToJSON and FromJSON instances for Natural, Positive, NotZero, and all newtype wrappers (ProductNatural, MaxNatural, MinNatural, SumPositive, MaxPositive, MinPositive, SumNotZero, MaxNotZero, MinNotZero)
  • Add toJsonNatural, parseJsonNatural, toJsonPositive, parseJsonPositive, toJsonNotZero, parseJsonNotZero functions
  • Add aeson dependency
  • Change Semigroup Positive from addition to multiplication
  • Remove Monoid Positive (no additive identity for positives)
  • Add SumPositive wrapper for addition of positives
  • Remove redundant notZero function (identical to _Positive on Natural)
  • Rename square to power, square1 to power1
  • Fix (!!) returning Nothing for index zero
  • Fix (!!!) off-by-one indexing
  • Fix minus1 producing Positive 0 when arguments are equal
