1. Shift Operators #

Created Sunday 28 June 2020

The basic ops for bits are shifts, there are two kinds:

Left shift #

• Left most bit(s) are lost.
• Value added to the right are zeroes(0), always.
• Syntax:

x << 1;
2 << 1;

• Significance of left shift: Multiplication by 2^k^.

Right shift #

• Right most bit(s) are lost.
• Value added to the left is 0 for positive and 1 for negative, i.e sign retained.
• Syntax:

x >> 1;
8 >> 1;

• Significance of right shift: Division by 2^k^, floor value.

Note: Shift behaves the same in all languages, because shifting is mathematical.
