Parse2DMultiExpr
Declaration:
EStackIndex
Parse2DMultiExpr
(HANDLE
hSrc
, BOOL
FullPrec
)
Category(ies):
Display
Description:
Parse a CAS expression on the estack into a 2D expression (graphical, as
opposed to linear text) output of the input. The expression to be parsed
may contain multiple expressions as follows (where * means 0 or more):
END_OF_SEGMENT_TAG { expr SEPARATOR_TAG } * expr.
Compare this to
Parse2DExpr
which only parses one expression.
Inputs:
hSrc
— HANDLE of data containing the CAS expression to convert
to 2D (it will be locked and unlocked as needed).
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).
