quantity :: (Ord i, Enum i, C a) => [Int] -> a -> T i aSource

Construct a physical value from a numeric value and the full vector representation of a unit.

fromScalarSingle :: a -> T i aSource

lift :: (a -> b) -> T i a -> T i bSource

apply a function to the numeric value while preserving the unit

errorUnitMismatch :: String -> aSource

addMaybe :: (Eq i, C a) => T i a -> T i a -> Maybe (T i a)Source

Add two values if the units match, otherwise return Nothing
