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


Syntax

result = FIX(expression)


Parameters

  • expression is any type of literal or variable numerical value or mathematical calculation.


Description

  • 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.
  • Use INT to round down negative values. Positive values are rounded down by both.


Examples

Example 1: Showing the behavior of FIX with positive and negative decimal point values.

 PRINT FIX(2.5)
 PRINT FIX(-2.5)
2
-2


Example 2: The NORMAL arithmetic method (round half up) can be achieved using the function in the example code below:

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
