The [[FIX]] function rounds a numerical value to the next whole number closest to zero.


{{PageSyntax}}
: {{Parameter|result}} = [[FIX]]({{Parameter|expression}})


{{Parameters}}
* {{Parameter|expression}} is any [[Data types|type]] of literal or variable numerical value or mathematical calculation.


{{PageDescription}}
* [[FIX]] effectively truncates (removes) the fractional part of {{Parameter|expression}}, returning the integer part.
** This means that [[FIX]] rounds down for positive values and up for negative values.
* Use [[INT]] to round down negative values. Positive values are rounded down by both.


{{PageExamples}}
''Example 1:'' Showing the behavior of [[FIX]] with positive and negative decimal point values.
{{CodeStart}} '' ''
 PRINT FIX(2.5)
 PRINT FIX(-2.5) '' ''
{{CodeEnd}} 
{{OutputStart}}2 
-2
{{OutputEnd}}


''Example 2:'' The NORMAL arithmetic method (round half up) can be achieved using the function in the example code below:
{{CodeStart}} '' ''
{{Cl|PRINT}} MATHROUND(0.5) 
{{Cl|PRINT}} MATHROUND(1.5)
{{Cl|PRINT}} MATHROUND(2.5)
{{Cl|PRINT}} MATHROUND(3.5)
{{Cl|PRINT}} MATHROUND(4.5)
{{Cl|PRINT}} MATHROUND(5.5)

{{Cl|FUNCTION}} MATHROUND(n)
    MATHROUND = {{Cl|FIX}}(n + 0.5 * {{Cl|SGN}}(n))
{{Cl|END FUNCTION}} '' ''
{{CodeEnd}} 
{{OutputStart}}1
2
3
4

6
{{OutputEnd}}
