(12C) Banker's Rounding Method
The banker's rounding method involves rounding numeric amounts to the nearest integer. When the number ends in 0.5 (1.5, 3.5, 8.5, etc), special rules apply:

The decimal gets rounded to the nearest even integer. For example: 0.5, 2.5, and 4.5 round down to 0, 2, and 4 respectively. However, 1.5, 3.5, and 5.5 are rounded up to 2, 4, and 6 respectively.
