I'm doing somethere where a selected value HAS to be an integer power of 2. Anyone know a "clean" way I could round a desired value to the nearest power of 2?

I.e. input is 37 -> rounded to 32

input is 84 - > rounded to 64

input is 99 -> rounded to 128

Just a general algo is fine, i can adapt it to PHP.
