{{Shared function}}<br />
<br />
This functions performs a bitwise circular left-rotation on the integer '''value''' by integer '''n''' positions.<br />
See [https://en.wikipedia.org/wiki/Bitwise_operation#Rotate_no_carry Bitwise operation] for more details.<br />
<br />
==Syntax==<br />
<syntaxhighlight lang="lua"><br />
int bitLRotate ( int value, int n )<br />
</syntaxhighlight><br />
<br />
===Required arguments===<br />
*'''value:''' The value you want to perform the rotation on.<br />
*'''n:''' The amount of positions to rotate the value by.<br />
<br />
===Returns===<br />
Returns the circular left-rotated value as ''integer''.<br />
<br />
==Example==<br />
This example shows the usage of the function [[bitLRotate]].<br />
<syntaxhighlight lang="lua"><br />
local value = 0xF -- binary: 1111, decimal: 15<br />
local positions = 0x1 -- binary: 0001, decimal: 1<br />
local shifted = bitLRotate( value, positions ) -- binary: 0001 1110, decimal: 30<br />
<br />
local value = 0xF -- binary: 1111, decimal: 15<br />
local positions = 0x3 -- binary: 0011, decimal: 3<br />
local shifted = bitLRotate( value, positions ) -- binary: 0111 1000, decimal: 120<br />
<br />
local value = 0x3F -- binary: 0011 1111, decimal: 63<br />
local positions = 0xA -- binary: 1010, decimal: 10<br />
local shifted = bitLRotate( value, positions ) -- binary: 1111 1100 0000 0000, decimal: 64.512<br />
