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.
