operand types, the rules for binary arithmetic operators apply. For
plain and long integers, the result is the same as
\code{(\var{a} / \var{b}, \var{a} \%{} \var{b})}.
For floating point numbers the result is the same as
\code{(math.floor(\var{a} / \var{b}), \var{a} \%{} \var{b})}.
For floating point numbers the result is \code{(\var{q}, \var{a} \%{}
\var{b})}, where \var{q} is usually \code{math.floor(\var{a} /
\var{b})} but may be 1 less than that. In any case \code{\var{q} *
\var{b} + \var{a} \%{} \var{b}} is very close to \var{a}, if
\code{\var{a} \%{} \var{b}} is non-zero it has the same sign as
\var{b}, and \code{0 <= abs(\var{a} \%{} \var{b}) < abs(\var{b})}.
