Embedded SQL "Nearest number" function?

(Please feel free to ignore this if you've got real work to do)

I know I can solve this by fetching through a cursor, but I thought I'd toss this up for someone to introduce me to a function that I've not yet discovered:

I need the row where a numeric column contains a number closest to (either greater or less than) a specified value.
Example: I want the row where ColumnA is closest to 1580.
Row# ColumnA
1 2016
2 1527
3 1874
4 4769
5 1600
6 158

Since there is no row with '1580', I would accept row 5, which is the closest. If there were two rows where the difference from the target value is the same (like if row 7 was added where ColumnA was 1560), I'd prefer the larger ColumnA value.
