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

{{PageSyntax}}
|
||
|
:: result = [[FIX]](''expression'')
|
||
|
|
||
|
|
||
|
* [[FIX]] effectively truncates (removes) the fractional part of ''expression'', returning the integer part.
|
||
|
* This means that [[FIX]] rounds down for positive values and up for negative values.
|
||
|
|
||
|
|
||
|
''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))
