Sourced from bigdecimal's releases.

v0.4.1

Changes

• Fix issue where RUST_BIGDECIMAL_DEFAULT_PRECISION envar would always trigger a rebuild

• Fix issue where .neg() could be called on {signed-int}::MIN values

• Add implementations of Add/Sub/Mul/Div for primitive values

• Use 'proptest' crate to improve arithmetic testing

v0.4.0

Changes

• no_std feature support akubera/bigdecimal-rs#97

  • To disable std, change your Cargo.toml dependency to:
    bigdecimal = { version = "0.4", default-features = false }
  • Still depends on alloc (I think we will always need dynamic storage)

• Allow user to set default max-precision at compile time

  • Use environment variable RUST_BIGDECIMAL_DEFAULT_PRECISION
  • Defaults to 100
  • This "is the number of 3s in calculation of 1/3"
  • Better solutions are being considered
    • This is tricky: Do we set a global variable? Do we require every math operation to specify precision? Do we store precision in each BigDecimal? Is that set from a global variable? Should we use macros to balance explicit precision and tidy code?

• Add rounding module with RoundingMode enum

  • Used in new method: BigDecimal::with_scale_round
  • Finally, you can truncate your decimal with the rounding you prefer!
  • Will be coming to more methods, soon

• Reimplement parsing from {32,64}-bit float values

  • Use binary bits instead of formatting to string and parsing
  • Already surprising users: akubera/bigdecimal-rs#103

• Bump Minimum Supported Rust Version from 1.34 to 1.43

  • Was breaking a few test dependencies
  • Able to do more at compile time
  • Probably wont affect too many people?

• Fix implementations of to_u128/to_i128 akubera/bigdecimal-rs#101

  • Default implementations cast values to 64 bit ints

• Fix issue where underscores after the decimal counted towards total digit count (giving wrong exponent) akubera/bigdecimal-rs#99

• Fix case of panic during rounding akubera/bigdecimal-rs#90

• Add preliminary benchmarking code

  • Unsatisfied with statistics: more work to be done with Criterion
  • Eventually get some answers on how best to parse strings, and in what format should the digits be stored

• Started using my crazy approach to unit testing

• f450e54 Release v0.4.1
• 1fc48f5 Version 0.4.1
• ccb6ccf Add alternative implementation of Div<int> for older versions
• 208831c Add autocfg to probe rust version
• 3510870 Pin serde json to 1.0.96
• 72bcd83 Merge proptest support into trunk
• 33232ce Enable property tests in gitlab-ci.yml
• 1d4f1d8 Add property-tests file
• 6515af3 Add support for proptests
• 65f9f8f Fix some rustfmt issues
• Additional commits viewable in compare view
