How to use this tool?
This guide explains how to use the Bit Shift Calculator to perform left and right bit shifts on decimal numbers.
- Enter a Decimal Number – Input any integer between -2,147,483,648 and 2,147,483,647 (e.g.,
8). - Set the Shift Amount – Enter a number from
0to31(e.g.,2) to specify how many bits to shift. - Choose the Direction – Select either Left Shift (
<<) or Right Shift (>>) from the dropdown. - Click "Calculate" – The result appears below, showing:
- The resulting decimal value.
- The 32-bit binary representation before and after the shift.
- The formula used (e.g.,
8 << 2 = 32).
Note: All numbers are treated as 32-bit signed integers. Left shifts multiply the number by 2shift; right shifts perform integer division by 2shift (truncating toward negative infinity).

Frequently Asked Questions
A bit shift moves the bits of a number left or right, effectively multiplying or dividing the number by powers of two.
Left shift (<<) multiplies the number by 2^shift, while right shift (>>) divides by 2^shift (floor division for integers).
The shift amount must be between 0 and 31 for 32-bit integers.
