## Charmed Price Problem

Published on Oct 6, 2014 in Excel Howtos Here is a charming little problem to kick start your day.

Lets say you run a cute little bakery around the corner. Since you want your prices to look charming, you have a policy to round them down or up based on below rule.

If the price ends with 0, 1 or 2 cents, round it down to 9 cents.

## Array formula to check if a number is prime [just for fun]

Published on May 29, 2009 in Learn Excel

I am math-geek-wannabe, if there ever is such a category. During my 3rd year of graduation I went and purchased the volume 2 of Donald Knuth’s Art of Computer Programming and thus began my love with all things random and prime. I never really became the math-geek I always wanted to, instead I became an insurance expert with tons of passion for data and visualization. But when I get a chance to poke with randomness or numbers, I always lap it up with joy. And that brings us to an interesting array formula trick to check if a number is prime or not.

=IF(MIN(MOD(\$B\$5,ROW(INDIRECT(“2:”&INT(SQRT(\$B\$5))))))=0,”not prime”,”prime”)

hit ctrl+shift+enter and bingo, it tells you if the number is prime or not. Read on to find how it works
