Synopsis

Documentation

The specific Value type returned by the evaluation

Arguments

:: Expr	the expression tree to evaluate
-> Either Error Double	the numeric result or an error

Evaluate an expression tree to a numeric value

Arguments

:: Expr	the expression tree to evaluate
-> Either Error EvalValue	the result or an error

Determine the result (value and dimension) of an expression tree

Combine the Units of two Dimensions, by adding the powers of matching units.

>>> mergeUnits [UnitExp Meter 2, UnitExp Second 1, UnitExp Kilogram 1] [UnitExp Meter 1, UnitExp Second (-2)]
m^3*kg/s

Combine the Units of two Dimensions, by subtracting the powers of matching units.

>>> subtractUnits [UnitExp Meter 2, UnitExp Second 1, UnitExp Kilogram 1] [UnitExp Meter 1, UnitExp Second (-2)]
m*s^3*kg
