FIX - mkilgore/QB64pe GitHub Wiki

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

result = FIX(expression)

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

• 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.

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:

FUNCTION MATHROUND(n)
    MATHROUND = FIX(n + 0.5 * SGN(n))
END FUNCTION '' ''
