BitCount() returns how many bits in the binary equivalent of a decimal number are set to 1. That is, the function returns the number of set bits in integer_number, where integer_number is interpreted as a signed 32-bit integer.
Syntax:
BitCount(integer_number)
Return data type: integer
Examples and results:
| Examples | Results |
|---|---|
| BitCount ( 3 ) | 3 is binary 11, therefore this returns 2 |
| BitCount ( -1 ) | -1 is 64 ones in binary, therefore this returns 64 |
