Added new _STRCMP and _STRICMP commands for quick string comparisons. Cleaned up QB64 to finish removing the QUI (quick user insert) code and folders. Altered UCASE and LCASE routines to be faster in some situations for us.

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

''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))
