Removing Numbers After a Decimal Point

10 posts in this topic

For example: 6.3 = 6 BUT 6.8 = 6

This means I can't simply use Round.

Is there any way of doing this without having to convert it to a string? I have a feeling there is a mathematical function that already does this.

Hi,

Take a look at the Floor or Int function.

You're welcome.

Next time, look at the helpfile. You will see the related functions.

I looked and found the int function but without looking at the example It isn't obvious that it works in that way. Actually scratch that I misread "Fractional portions are truncated, so Int(1.999999) returns 1"

Remark that Int() and Floor() are not identical functions over the reals:

ConsoleWrite(Int(1.9876) & "  " & Floor(1.9876) & @LF)
ConsoleWrite(Int(-1.9876) & "  " & Floor(-1.9876) & @LF)

can use StringMid and StringInStr too.

$number = "6.3"
$extract = StringMid($number, 1, StringInStr($number, ".", 2, 1) -1)
MsgBox(4096, "test", $extract)

Anyway a numeric string can be lead to contradictory results:

$number = "1.9999999999999999999"
$extract = StringMid($number, 1, StringInStr($number, ".", 2, 1) -1)
MsgBox(4096, "test", $extract)
