Subject: Next lowest number from array (or list).
Say that I have a list of allowed nmbers:
32,48,64,72,144,160,200,288,320,400,512,576,640,720,800
If I give the user the option of selecting a number, and it happens to not
be in this list, how might I go about automagically selecting the next
lowest number? One exception being if the user selects a number lower than
32, in which case the code should return 32.
Examples:
User selects 100, the code would return 72.
User selects 480, the code would return 400.
User selects 25, the code would return 32.
Currently the numbers are stored in a simple list, but I have control over
that list and they can be in whatever format makes the most sense. One
caveat is that they need to stay in code (so no database interaction).
