/**
|
|
* Bitwise left logical shift of a value x by y number of bits, `x << y`.
|
|
* For matrices, the function is evaluated element wise.
|
|
* For units, the function is evaluated on the best prefix base.
|
|
*
|
|
* Syntax:
|
|
*
|
|
* math.leftShift(x, y)
|
|
*
|
|
* Examples:
|
|
*
|
|
* math.leftShift(1, 2) // returns number 4
|
|
*
|
|
* math.leftShift([1, 2, 4], 4) // returns Array [16, 32, 64]
|
|
*
|
|
* See also:
|
|
*
|
|
* leftShift, bitNot, bitOr, bitXor, rightArithShift, rightLogShift
|
|
*
|
|
* @param {number | BigNumber | bigint | Array | Matrix} x Value to be shifted
|
|
* @param {number | BigNumber | bigint} y Amount of shifts
|
|
* @return {number | BigNumber | bigint | Array | Matrix} `x` shifted left `y` times
