Everyone knows about the ROUND function for converting floating point values to their nearest whole number or integer value, but have you ever wanted to round off values to something other than whole numbers? This simple utility function does just that.
Example 1: round PI to 2 decimal places
>> round2(pi,0.01)
ans =
3.14

Example 2: round PI to 4 decimal places
>> round2(pi,1e-4)
ans =
3.1416

Example 3: round PI to 8-bit fraction
>> round2(pi,2^-8)
ans =
3.1406

Examples 4-6: round PI to other multiples
>> round2(pi,0.05)
ans =
3.15
>> round2(pi,2)
ans =
4
>> round2(pi,5)
ans =
5
