Excel Made Easy - How to Round, Round Up and Round Down in Microsoft Excel

In Microsoft Excel, the functions ROUNDUP and ROUNDDOWN are used to round numbers to a specified number of digits, either up or down, regardless of the number being rounded.

### ROUNDUP Function
- **Syntax:** `ROUNDUP(number, num_digits)`
- **Parameters:**
- `number`: The number you want to round up.
- `num_digits`: The number of digits to which you want to round the number. If positive, rounds up to the right of the decimal point; if zero, rounds up to the nearest integer; if negative, rounds up to the left of the decimal point.
- **Behavior:** Always rounds the number away from zero, ensuring the result is greater in magnitude.

### ROUNDDOWN Function
- **Syntax:** `ROUNDDOWN(number, num_digits)`
- **Parameters:**
- `number`: The number you want to round down.
- `num_digits`: The number of digits to which you want to round the number. If positive, rounds down to the right of the decimal point; if zero, rounds down to the nearest integer; if negative, rounds down to the left of the decimal point.
- **Behavior:** Always rounds the number towards zero, ensuring the result is less in magnitude.

These functions are useful for controlling the precision of numerical data and ensuring consistency in rounding behavior, particularly in financial calculations or when dealing with measurements.
