Q&A How to calculate the Hamming weight of a binary string?

I believe the answer at the moment is "No" but a very simple formula in LibreOffice 5.4.3.2 can achieve the desired result: =LEN(SUBSTITUTE(B1;0;"")) where B1 contains: =BASE(A1;2;8) as valid and...

  • I believe the answer at the moment is "No" but a very simple formula in LibreOffice 5.4.3.2 can achieve the desired result:
  • =LEN(SUBSTITUTE(B1;0;""))
  • where B1 contains:
  • =BASE(A1;2;8)
  • as valid and A1 contains the number in decimal.
  • The B1 cell would not be required with this version:
  • =LEN(SUBSTITUTE(BASE(A1;2;8);0;""))
  • This converts to binary, strips out the `0`s and counts the number of characters left thereafter.
  • With the appropriate delimiter, should also work in Excel, Sheets and OpenOffice Calc.

I believe the answer at the moment is "No" but a very simple formula in LibreOffice 5.4.3.2 can achieve the desired result:

    =LEN(SUBSTITUTE(B1;0;""))

where B1 contains:

    =BASE(A1;2;8)

as valid and A1 contains the number in decimal.

The B1 cell would not be required with this version:

    =LEN(SUBSTITUTE(BASE(A1;2;8);0;""))

This converts to binary, strips out the `0`s and counts the number of characters left thereafter.

With the appropriate delimiter, should also work in Excel, Sheets and OpenOffice Calc.
