RDD - Round Down #
Round Down uses similar logic to Round Nearest, but rounds down to the last level specified in Operand 3
Examples
| Operand 2 | Operand 3 | Result (stored in Operand 1) |
|---|---|---|
| 1.10011 | 1 | 1 |
| 1.10011 | 0.001 | 1.100 |
| 1.1 | 0.5 | 1.0 |
| 1.0 | 0.5 | 1.0 |
| 1.9 | 0.5 | 1.5 |
As with RDN, it is acceptable to round down to the next .25, or any other amount such as to the next 2, 3, etc.
Statement: Round the value of PC 500 down to the nearest quarter hour and store it back into itself.
