Find closest value in a multidim array

Last Modified: 2014-07-22
I have a multidim array that has hundreds of records and it.
For array(i, 2) the data looks like this:

array(0,2) = 121
array(1,2) = 3121
array(2,2) = 5121
array(3,2) = 6121

I perform a calculation and get a random value of 4010 and want to search the array(I, 2) for the closest (rounded up) value in the array.

What's the best way of going about this.
