Multiplication

Note

This page concerns the * operator on numbers; for the * operator on types, see pair types; or see the * (connect) operator on graphs.

All numeric types can be multiplied using the * operator. For example:

Disco> 2 * 3
6
Disco> (-5) * 2/3
-10/3

In some cases, the * symbol is not needed: putting two things next to each other means multiplying them. For example:

Disco> (1 + 2)(3 + 4)
21
Disco> x : N
Disco> x = 5
Disco> 3x
15

The exception is that putting a variable directly on the left of something else is interpreted as function application instead of multiplication.
