UNIT ( expression )
Implemented in iMath since version 2.2.0 or earlier.
Explanation
Try to find a quantity (number with optional units) for the expression from any equations defined previously in the document, and then get the units of this result. Gives an error if the expression does not evaluate to a quantity.
Example
EQDEF a = 3 x
EQDEF b = 2 x
EQDEF x = 7 %metre
EXDEF UNIT(a + b)
This will output "m".
