left Euclidean division of ordinals
left Euclidean quotient of ordinals
left Euclidean remainder of ordinals
ordinals, nonnegative integers, or polynomials with positive integer coefficients
Div returns an expression sequence q, r such that a=b⋅q+r, where q and r are ordinals, nonnegative integers, or polynomials with positive integer coefficients, and r is as small as possible.
quo returns just q and rem returns just r.
The Div(a, b) calling sequence computes the unique ordinal numbers q and r such that a=b⋅q+r and r≺b, where ≺ is the strict ordering of ordinals.
If b=0, a division by zero error is raised.
The ordinal a is left divisible by b if and only if r=0.
If one of a and b is a parametric ordinal and the division cannot be performed, an error is raised.
The quo and rem commands overload the corresponding top-level routines quo and rem, respectively. The top-level commands are still accessible via the :- qualifier, that is, :-quo and :-rem, respectively.
Any of the arguments can be an integer.
Error, (in Ordinals:-Div) division by zero
Error, (in Ordinals:-Div) unable to divide
The Ordinals[Div], Ordinals[quo] and Ordinals[rem] commands were introduced in Maple 2015.
