Syntax
QUANTITY ( 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. Gives an error if the expression does not evaluate to a quantity.
All numerical values will be converted to floating point numbers. If you do not want this, use VAL instead.
Example
EQDEF a = 3 x
EQDEF b = 2 x
EQDEF x = 7 %metre
EXDEF QUANTITY(a + b)
This will output 35 "m".
