Bert Wagner reminds us that integer math is a thing:
To determine how much lumber I would need for building the new walls, I decided to write a SQL query to help with my framing calculations. I was building a 6 foot wall and wanted to put a stud every 16 inches. Easy enough to do the math on this:
SELECT (6*12)/16The output of the query above was 4, indicating the number of studs I would need for one wall section.
What’s interesting is that if we do this same equation in a calculator, we get a slightly different answer: 4.5.
