Try to find a quantity (number with optional units) for the expression from any equations defined previously in the document, plus the equations given as the second argument. 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.

EXDEF QUANTITYWITH(a + b, x = 7 %metre)

This will output 35 "m".
