List Commands Library for 50g

For example:

Code:

{ 1 2 3 4 5 } 1.1 GET

returns 1

whereas

Code:

{ 1 2 3 4 5 } 1.8 GET

returns 2

I think rounding is more appropriate. Consider the case where where some calculation is used to compute the index. If the calculation results in an index of 0.999999999 or 1.000000001, the result of GET should probably be the same.

On the other hand, I can't recall a single instance in decades of programming where I've needed complex calculations to compute an index that would result in needing rounding.
