Elm 0.18 replaced some functions from Elm 0.17 with flipped versions. So, here are the original unfipped versions.
shiftLeft : Basics.Int -> Basics.Int -> Basics.Int
Shift bits to the left by a given offset, filling new bits with zeros. This can be used to multiply numbers by powers of two.
8 `shiftLeft` 1 == 16
8 `shiftLeft` 2 == 32
shiftRight : Basics.Int -> Basics.Int -> Basics.Int
Shift bits to the right by a given offset, filling new bits with whatever is the topmost bit. This can be used to divide numbers by powers of two.
32 `shiftRight` 1 == 16
32
`shiftRight` 2
== 8
- 32
`shiftRight` 1
== -16
This is called an arithmetic right shift, often written (>>), and sometimes called a sign-propagating right shift because it fills empty spots with copies of the highest bit.
shiftRightLogical : Basics.Int -> Basics.Int -> Basics.Int
Shift bits to the right by a given offset, filling new bits with zeros.
32 `shiftRightLogical` 1 == 16
32
`shiftRightLogical` 2
== 8
- 32
`shiftRightLogical` 1
== 2147483632
This is called an logical right shift, often written (>>>), and sometimes called a zero-fill right shift because it fills empty spots with zeros.
