AVAL

Syntax

AVAL ( expression )

Implemented in iMath since version 2.2.6.

Explanation

Try to find a value for the expression from any equations defined previously in the document. The expression will not be reduced to floats, e.g. square roots of rational numbers and transcendental functions will remain in the result. If you want to force a conversion to floats, use QUANTITY instead.

Example

EQDEF a = 3

EQDEF x = 1 over 2

EXDEF VAL(a^x + sin(x))

This will output sqrt{3} + sin(1/2).
