Version 0.1.14

Changes in this version:

• Add support for strings and string literals. They can be in single or double quotes, and support a variety of escape sequences.
• Support conversions of numbers to strings
• Use b as shorthand for bits (including e.g. Gb/s)
• Remove the 0d number prefix

Version 0.1.13

Changes in this version:

• Add °C and °F (including temperature conversions)
• Automatically simplify units in some calculations (e.g. 100 km/hr * 36 seconds becomes 1 km)
• Add initial support for objects (try e.g. mass of earth)
• Add square and cubic functions
• Add hectares and acres

Version 0.1.11

Changes in this version:

• Improve debug representation (using e.g. !debug 1)
• Use camel-case function names in fend-wasm

Version 0.1.10

Changes in this version:

• Allow leading zeroes for decimal numbers
• Allow upper-case "E" for exponential numbers (e.g. 1E3 is 1000)
• Add in as an alias for to (so you can now write 3.14 in binary)
• Add log() function as shorthand for log10()
• Fix kWh unit definition

Version 0.1.9

Changes in this version:

• Include LICENSE.md files as part of the package on crates.io

Version 0.1.8

Changes in this version:

• Add 'version' command to get the current fend version
• Support -sin pi and 3 sin pi without parentheses
• Support function inverses: e.g. sin^-1 becomes asin
• Add to sf to convert numbers to a fixed number of significant figures
• Make many calculations involving sin and cos exact
• Add tau (τ), equal to 2π
• Add Yi- and Zi- binary prefixes
• Use decimal approximations instead of fractions by default
• x to exact will now convert x to an exact representation whenever possible, including using multiples of π
• Add cis as a shorthand for cos θ + i * (sin θ)

Version 0.1.7

Changes in this version:

• Ensure that approximate numbers are always marked as such
• Fix a bug involving sin/cos/tan of negative numbers
• Make some calculations involving pi exact
• Fix parsing of recurring decimals in bases other than 10
• Add a changelog command to the command-line interface

Version 0.1.6

Changes in this version:

• Support parsing of numbers with recurring digits (e.g. 0.(3) is equal to 1/3)
• Support outputting mixed fractions (implicitly or via to mixed_fraction)
• Support unmatched parentheses (e.g. 2+3)*(1+2 is 15)
• Allow numbers that start with a decimal point, such as .1

Version 0.1.5

Changes in this version:

• Add support for lambda functions (e.g. \x.x or (x: 2x) pi)
• Add live CLI output
• Change precedence of to, as and ->

Version 0.1.4

Changes in this version:

• Add the GNU units database, which contains several thousand unit definitions
• Add support for square roots of numbers with units
• Add unary division as a shorthand for 1/x (e.g. / second, 64^/2)
• Support + in exponential notation (e.g. 1.5e+2)
• Allow , as a digit separator (e.g. 1,048,576)
