Integer.Extension (ESpec v1.10.0)
View SourceA module to extend the calendar implementation that follows to ISO8601 with methods found in Elixir 1.5.1. This is to allow ESpec to support Elixir >= 1.3.4 more easily.
Summary
Functions
Performs a floored integer division.
Functions
@spec floor_div(integer(), neg_integer() | pos_integer()) :: integer()
Performs a floored integer division.
Raises an ArithmeticError
exception if one of the arguments is not an
integer, or when the divisor
is 0
.
Integer.floor_div/2
performs floored integer division. This means that
the result is always rounded towards negative infinity.
If you want to perform truncated integer division (rounding towards zero),
use Kernel.div/2
instead.
Examples
iex> Integer.floor_div(5, 2)
2
iex> Integer.floor_div(6, -4)
-2
iex> Integer.floor_div(-99, 2)
-50
