Ones counter tool
What is a ones counter?

This utility calculates the number of ones in binary values. It can count the high bits in binary numbers of any length. It can also process multiple binaries at once if they are entered one per line. With the multiline option active, it displays the number of 1's for each value individually. If option multiline is turned off, it displays the total number of ones in all binary values. The binary representation can also be prefixed or suffixed with the binary base indicator. For example, "0B101", "101b", or "101₂". The presence of a base indicator does not affect the number of high bits. Simple and easy!

Ones in Binary Number

In this example, we calculate the number of 1's in the decimal number 54483 that's written in the binary representation. The input number contains sixteen bits and nine of them are ones.

1101010011010011

9

**Required options**

Count the number of ones
in each line separately.

Prefixed Binaries

In this example, we count the number of set bits in seven binary numbers that have binary base prefixes or suffixes. We use the "Multiline" option so that the calculation is carried out individually for each line.

1024-bit RSA Key

This example processes a large 1024-bit binary private key and calculates the number of ones in it. It turns out that in this number there are 508 symbols that are '1' and the rest 516 (1024-508) symbols are '0'.
