| =MROUND(-10, -3) | Rounds -10 to the nearest multiple of -3. | -9 |
| =MROUND(1.3, 0.2) | Rounds 1.3 to the nearest multiple of 0.2. | 1.4 |
| =MROUND(5, -2) | Returns the #NUM! error message because -2 and 5 have different signs. | #NUM! |

When a decimal value is provided to the Multiple argument , the rounding direction is undefined for midpoint numbers. For example MROUND(6.05,0.1) returns 6.0 while MROUND(7.05,0.1) returns 7.1.
