fend 1.5.3

Version 1.5.3

on Rust Cargo

Changes in this version:

• Add support for using commas rather than dots as the decimal separator, as is common in many European languages. This can be enabled by setting decimal-separator-style = "comma" in ~/.config/fend/config.toml, and it changes e.g. 1.23 to 1,23, or 1,234.00 to 1.234,00.
• Support large roman numerals beyond 1000 using overlines, e.g. 15400 to roman is X̅V̅CD. Numerals with an overline are 1000 times larger, so V̅ is 5,000, X̅ is 10,000 etc. Note that these numbers may not be displayed correctly if your terminal doesn't have full Unicode support.
• Improve accuracy of logarithms and support logarithms with operands larger than 2^1023, e.g. log2 10^1234 now works correctly.
• Add light_speed/lightspeed unit, equivalent to the existing constant c
• Allow adding 0 regardless of units in some situations, e.g. 1 km + 0. This works because zero is the additive identity.
