NUMVAL (expression )
Implemented in iMath since version 2.2.0 or earlier.
Explanation
Try to find a purely numeric value for the given expression from any equations defined previously in the document. An error is produced if the expression does not evaluate to a number.
If any units are found in the result, a warning message will be logged and the units are removed.
Example
EQDEF a = 3 x
EQDEF b = 2 x
EQDEF x = 7
EXDEF NUMVAL(a + b)
This will output 35.
