Morten Piibeleht 8ebb2c791b Partially revamp the HalfInteger type (#4) ... * Call the HalfInteger field twofold Makes it more immediately obvious what the meaning of the value stored in the field is. * Introduce new constructors for HalfInteger The primary inner constructor mirrors the two-argument constructor of the Rational type, where the user provides the numerator and denominator values. There is also a single argument outer constructor that makes HalfInteger behave like a normal numeric type such that HalfInteger(n) == n. * Move HalfInteger tests to a separate file The using statements in halfinteger.jl are there so that it would be possible to run the file separately from the other tests. * Test the single-argument HalfInteger constructor * Organize halfinteger.jl a bit Prioritise the convert methods. * Add multiplication with integer to HalfInteger * Implement parsing and printing for HalfInteger * parse(::HalfInteger, x) method * Overload show to pretty-print HalfInteger * Overload Base.numerator/denominator And add tests for the other supplementary functions and methods as well. * Add HalfIntegerRange type Can be constructed using the range operator :. Currently only supports unit steps in the positive direction. * Address feedback * Rename .twofold -> .numerator * Consistent variable names * Remove unnecessary methods for HalfIntegerRange * Allow constructing HalfIntegerRange with non-integer difference * Add docs and ceil(::HalfInteger)		2019-01-10 21:50:46 +01:00
