How can I do floor division in Julia?

Solution

  • Try:

    julia> 5 ÷ 2
2

    The character ÷ can be entered by typing \div and pressing Tab.

    On the other hand the operator // is used to create rational numbers.

    The ÷ sign represents a div operator. If the number is negative you need to use fld to the the actual floor division. You could assign it to one of unused operators for comfortable use:

    julia> ∺ = fld
fld (generic function with 10 methods)

julia> -5 ∺  2
-3
