v0.6.0

Breaking changes

• Removed previously deprecated Decimal methods:
  • from_scale (use quantum instead).
  • normalized (use reduce instead).
  • with_scale (use rescale instead).

Added

• Decimal truncation API (#39):
  • Decimal::trunc() — truncates to integral with no fractional portion without rounding.
  • Decimal::trunc_with_scale(scale) — truncates to the specified scale without rounding.

Changed

• Internal documentation macro routing for decimal type aliases refined (no public API impact).

Documentation

• Minor fixes.
• Added a dedicated “Truncate” section with behavior details and examples.

Internal

• Introduced an internal truncation implementation integrated with scaling and extra-precision handling to ensure true
  truncation semantics (no rounding).
