A shitty dimensional analysis calculator in haskell
- hastily written in a day
- not extensively tested
- written by a haskell noob
- not very consistent syntax
The programme takes in the input string as the first command line argument.
??? stands for the unknown unit you're trying to solve for. Multiplication is using spaces ( ), division is by /,
associativity is preserved.
I think its easiest to show some examples:
Wb = ???kg m ??? = kg m s^-2s^-8 kg^3 m^3 A^-4 ??? / ( kg^2 m^4 s^-6 A^-4 ) = kg m^2 s^-2( kg / (N / m) )^(1/2) = ???
You can run this like any other cabal project, cabal run dim-analysis-tool -- '<your input>'.
The derived SI units on this wikipedia page are supported
(with the ohm literally spelt ohm instead of the unicode omega).
The parser is case sensitive but extra whitespace shouldn't be an issue.
- Doing
s^(2)doesn't work, but you must dos^(1/2)ors^(-1/2)if you want fractions (not bothered to fix this)
