Declaration:
void
push_arg_plus_1
(EStackIndex
i
)
Category(ies):
EStack Arithmetic
Description:
Pushes onto the estack the internally-simplified sum of the expression
i
plus 1.0 if IS_ARITH_APPROX, or the expression
i
plus 1 otherwise. If
i
indexes a square matrix, the one is added only to the diagonal of the
matrix.
Inputs:
i
— Index to an internally-simplified algebraic expression, algebraic
comparison, or aggregate thereof.
Outputs:
None

i
points to the top tag of an internally-simplified algebraic expression,
algebraic comparison, or aggregate thereof.
Side Effects:
None
Availability:
On AMS 2.02 and higher.
