Syntax

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.
