Syntax

REALVARDEF symbol


Implemented in iMath since version 2.2.0 or earlier.

Explanation

Defines the symbol to be real-valued. This allows iMath to evaluate some functions immediately, e.g. complex conjugation.


Example

REALVARDEF x tells iMath that x always has a real value and therefore conjugate(x) = x.
