/ -- a binary operator, usually used for division
Synopsis
Usage:
x / y
Description
This operator is currently used in several ways in Macaulay2.
division in a ring, yielding a fraction
division in unevaluated expressions
quotient rings, modules and sheaves
applying a function or ring map to every element of a list or set

For the programmer
The object
/
is
a
keyword
.
This operator may be used as a binary operator in an expression like
x/y
. The user may install
binary methods
for handling such expressions with code such as
X / Y := (x,y) -> ...
where
X
is the class of
x
and
Y
is the class of
y
.
