This commit adds a number library which handles fractions, floats, whole numbers, scientific notation, and special symbolic numbers all according to the R7RS small specification. Numeric trait is used to abstract operations across all number types and a Number enum is used to offer a non-opaque type that stores any kind of number. Upon the Number enum is implemented the following traits: - Add, Div, Sub, Mul - Pow - PartialEq - PartialOrd Which then offer the following operators to use on the Number enum instances themselves: + - / * == != < > <= >= and of course x.pow(y). Additionally, the number package contains parsing logic for each type of number. FromStr is implemented as part of the Numeric trait, and then in turn implemented on Number. Additionally Into<String> is implemented for the Numeric trait and then on the Number enum type as well. Test cases have been added for basic cases, but could be expanded. Additional modifications: - LexError has a custom display implementation that properly outputs formatted errors. - Sexpr package updated to use new number package Signed-off-by: Ava Affine <ava@sunnypup.io> |
