How does the left shift operator work?
The left shift operator ( << ) shifts the first operand the specified number of bits to the left. Excess bits shifted to the left are discarded. Zero bits shift from the right.

What is the effect of shifting to the left?
Left shifting n bits in a signed or unsigned binary number has the effect of multiplying it by 2n. Shifting n bits right in a two’s complement signed binary number has the effect of dividing it by 2n, but it always rounds down (to negative infinity).
How do the left and right shift operators work?
Bitwise shift operators shift the bit values of a binary object. The left operand specifies the value to be shifted. The right operand specifies the number of positions the bits in the value will be shifted. Both operands have the same precedence and are associative from left to right.
Why is shift left important?
A greater shift to the left indicates a greater consumption of neutrophils in the blood. A larger left shift represents a more serious bacterial infection. The shift to the left reflects the severity of a neutrophil-consuming bacterial infection. An elevated white blood cell count shows a sufficient supply of neutrophils to the infected site.
What is the left shift principle?
The principle of Shift Left is to take a task that is traditionally done later in the process and perform it earlier. An example of this is testing. With the traditional waterfall model, testing is done just before the product is released into production.
Why do we use Shift?
The shift operator is used when performing logical bit operations, as opposed to mathematical operations. It can be used for speed, being significantly faster than division/multiplication when dealing with operands that are powers of two, but code clarity is generally preferred over raw speed.
What does a shift to the left indicate?
A “left shift” is a phrase used to signal that young/immature white blood cells are present. Most commonly, this means there is an infection or inflammation and the bone marrow is making more white blood cells and releasing them into the blood before they fully mature.
What does a left shift mean?
A shift to the left indicates the presence of immature neutrophils in the blood and usually, but not always, indicates an inflammatory leukogram (see related links for the historical origin of this term). Some concepts associated with a shift to the left: A shift to the left may be due to the release of bone marrow reserves.
