The [FIX](FIX) function rounds a numerical value to the next whole number closest to zero.
|
||
|
|
|
||
|
|
## Syntax
|
||
|
|
|
||
|
|
> result = [FIX](FIX)(expression)
|
||
|
|
|
||
|
|
## Parameter(s)
|
||
|
|
|
||
|
|
* expression is any [Data types](Data-types) of literal or variable numerical value or mathematical calculation.
|
||
|
|
|
||
|
|
## Description
|
||
|
|
|
||
|
|
* [FIX](FIX) effectively truncates (removes) the fractional part of expression, returning the integer part.
|
||
|
|
* This means that [FIX](FIX) rounds down for positive values and up for negative values.
|
||
|
|
* Use [INT](INT) to round down negative values. Positive values are rounded down by both.
|
||
|
|
|
||
|
|
## Example(s)
|
||
|
|
|
||
|
|
Showing the behavior of [FIX](FIX) with positive and negative decimal point values.
|
||
|
|
|
||
|
|
```vb
|
||
|
|
|
||
|
|
PRINT FIX(2.5)
|
||
|
|
PRINT FIX(-2.5)
|
||
|
|
|
||
|
|
```
|

The NORMAL arithmetic method (round half up) can be achieved using the function in the example code below:
|
||
|
|
|
||
|
|
```vb
|
||
|
|
|
||
|
|
PRINT MATHROUND(0.5)
|
||
|
|
PRINT MATHROUND(1.5)
|
||
|
|
PRINT MATHROUND(2.5)
|
||
|
|
PRINT MATHROUND(3.5)
|
||
|
|
PRINT MATHROUND(4.5)
|
||
|
|
PRINT MATHROUND(5.5)
|
||
|
|
|
||
|
|
FUNCTION MATHROUND(n)
|
||
|
|
MATHROUND = FIX(n + 0.5 * SGN(n))
|
||
|
|
END FUNCTION
|
||
|
|
|
||
|
|
```
