Declaration:
EStackIndex
Parse2DExpr
(EStackIndex
i
, BOOL

)
Category(ies):
Display
Description:
Parse a CAS expression on the estack into a boxed RPN representing the
2D (graphical, as opposed to linear text) output of the RPN.
Inputs:
i
— EStackIndex of CAS expression to convert to 2D.
FullPrec
— If TRUE, floating-point numbers are converted to full float
precision. Otherwise, they are printed with the current
precision set by the MODE screen.
Outputs:
Return the EStackIndex of the boxed RPN. If there is not enough memory
then a special symbol is pushed onto the estack to signify this.
Assumptions:
None
Side Effects:
May compress the heap. May throw the following errors: ER_MEMORY
(very low memory) and ER_BREAK (
´
pressed while converting).
