| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Until this commit, `int` and `float` were special types in Pint (just as they are in Python). Numbers were parsed from strings as int/float from the definition files and from user provided strings; and exponents of units were also stored as int/float. This commit change this by adding a new argument (`non_int_type`) to classes and methods. It indicates how numeric values will be parsed and defaulted. Any numerical class can be used such as `float` (default), Decimal, Fraction. This argument will be found in the following places 1. UnitRegistry: used for parsing the definition files and any value provided as a string. 2. UnitsContainer: used to compare equality with strings, multiply and divide by strings (which is equivalent to parse the string) 3. All methods OUTSIDE the UnitRegistry/Quantity that can parse strings have a `non_int_type` argument. (e.g. Definition.from_string) Tests have been added for by duplicating most cases in `test_quantity.py`. (Some tests have been deleted such as those dealing with numpy.) The new file `test_non_int.py` run the tests for `Decimal`, `Fraction` and `float` (which is redundant but is kept as a crosscheck for the implementation of this testsuite) BREAKING CHANGE: `use_decimal` is deprecated. Use `non_int_type` keyword argument when instantiating the registry. >>> from decimal import Decimal >>> ureg = UnitRegistry(non_int_type=Decimal)
| * Replace 1.0 and 0.0 (floats) by 1 and 0 (integers)Hernan2020-01-211-2/+2
| | | | | | | | | | | | | | | | | | | | In the original codebase, many accumulators, default values and so on were initialized with floats (instead fo integers). The reason behind this decision was that in Python 2 the division (/) was by default an integer division if all values were ints. Therefore, using a float ensured "the right result". Now that the codebase is Python 3, we can safely use integers everywhere. This wil be helpful when a different non integer type is desired.

| | | | | | | | | | | | | | | | | | 1. UnitRegistry now has an optional keyword argument (`locale`) that can be used to define the default value for `Quantity.format_babel` locale argument. 2. When Babel is not installed, `Quantity.format_babel` display a nicer and more informative exception. Closes #899, #904

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The module defines 5 registries with different capabilites: - BaseRegistry: Basic unit definition and querying. Conversion between multiplicative units. - NonMultiplicativeRegistry: Conversion between non multiplicative (offset) units. (e.g. Temperature) * Inherits from BaseRegistry - ContextRegisty: Conversion between units with different dimenstions according to previously established relations (contexts). (e.g. in the spectroscopy, conversion between frequency and energy is possible) * Inherits from BaseRegistry - SystemRegistry: Group unit and changing of base units. (e.g. in MKS, meter, kilogram and second are base units.) * Inherits from BaseRegistry - UnitRegistry: Combine all previous capabilities, it is exposed by Pint. There is performance penalty in some functions (< 10%) maybe due to method calls but the code is cleaner a easier to understand.

The implementation is added in a separate, independent file for prototyping. Functions are written independent of the Registry. Test for Groups are added.
