0.9.0

Changes

• The micro symbol ('µ'), U+00B5, is now accepted as a valid prefix when creating prefixed.Float objects from strings
  • Output will still use the lowercase Greek letter mu ('μ'), U+03BC
  • This complies with the preference defined in Unicode Technical Report #25 section 2.5
  • A note was added to the documentation for reference

0.8.0

• Bugfixes
  • Rounding was not accounted for when determining prefixed
    • For example, f'{Float(9.999999999e-10):.2H}' returned 1000p rather than 1n
    • Rounding is now accounted for when determining prefix

0.7.1

Housekeeping

• Metadata updates

0.7.0

Changes

• Magnitude values are read from a dictionary rather than computed
  • This should result in faster and more consistent behavior

0.6.0

Changes

• Consistent behavior for ! flag

  • The ! flag used to drop the space when no prefix was added to the output
  • This created issues in cases like f'{Float(123):!.3H}J' #4
  • ! will now always add a space after the number

• New flag !!

  • The new flag !! operates like !, adding a space between the number and the prefix
  • !! will drop the space if no prefix is added to the number
  • See the documentation for more information

0.5.0

Changes

• Add new SI prefixes

  • Added at November 2022 General Conference on Weights and Measures

  Prefix	Name	Base
  Q	quetta	10³⁰
  R	ronna	10²⁷
  r	ronto	10⁻²⁷
  q	quecto	10⁻³⁰

Bugfixes

• In some circumstances significant digits were one decimal place off
  • Caused by floating point variance
  • Value is now constrained prior to determining significant digits

0.4.2

Bug Fixes

• Deprecated format specifiers 'j' and 'J' were not properly handled when passed as Unicode in 2.7
  • Fixed and test added to catch regressions

0.4.1

Bug Fixes

• Deprecated format specifiers 'j' and 'J' were not properly handled
  • Fixed and test added to catch regressions

0.4.0

Changes

• Add Significant digit support
  • 'H' (SI), 'K' (IEC), and 'M' (IEC short) presentation types treat precision as significant digits
  • Trailing zeros are dropped by default, use '#' to preserve
• 'j' (IEC) presentation type replaced with 'k'
  • 'j' still works, but is deprecated
• 'J' (IEC short) presentation type replaced with 'm'
  • 'J' still works, but is deprecated
• Dropped support for Python 3.4

Housekeeping

• Moved to GitHub Actions
• Rename master to main

0.3.2

Changes

• No longer accept arbitrary characters after prefix in input strings
• Accept a single space between value and prefix in input strings

Bug Fixes

• Base for IEC values was incorrect in documentation
