Bits Required for Number Calculator
Determine how many bits are needed to encode a non-negative integer in binary.
CalcSimpler Examples
- 15 ⇒ 4 bits
- 1023 ⇒ 10 bits
FAQ
Why add one before taking log2?
It ensures exact bit count for powers of two.
What if the number is zero?
Zero requires 1 bit (value 0).
Can it handle large numbers?
Yes, as long as they fit in JavaScript's numeric range.
Is this for signed integers?
No, it calculates bits for unsigned representation.
Additional Information
- log2 computes the base-2 logarithm.
- Binary digits (bits) are fundamental units of digital data.
