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.

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