  10
  

Version 1.1.4

Changes in this version:

• Add support for subtracting from dates (e.g. @2023-01-08 - 5 days)
• Fix some trigonometric functions behaving incorrectly when passing in values with units

Version 1.1.3

Changes in this version:

• Add operators for permutations and combinations (by @frectonz)
  • n permute k or n nPr k: compute the number of k-permutations of n
  • n choose k or n nCr k: number of k-combinations of n
• Add @noapprox attribute to hide the approx. annotation in the output:

  > pi
  approx. 3.1415926535
  > @noapprox pi
  3.1415926535
  

• Add @plain_number attribute, to remove approx. and any units. This is especially useful in automated scripts.

  > 5 m / (3 s)
  approx. 1.6666666666 m / s
  > @plain_number 5 m / (3 s)
  1.6666666666

  • >>: right shift

Version 1.1.0

Changes in this version:

• Automatically download up-to-date currency exchange rates, e.g. when calculating 10 EUR to USD

• Shebangs (e.g. #!/usr/bin/env fend) no longer result in parse errors
• You can now use -- to force fend to interpret arguments literally, e.g. fend -- -V is interpreted as -1 volts instead of showing the version number

• Add a man page
• Add an MSI installer for Windows
