Rounding down / truncating numbers in ASP 1

[xjs]

Does anyone know how to strip a decimal so that a rounded down integer is returned? Would I have to parse text from the number and remove the decimal and everything to the right of it?

It sounds like it should be easy but I can't find what I need on the web. Am I missing something?

Thanks.

how's this for a ugly function
Dim var, str
str = 123.32
var = Left(str, instr(str,".&quot-1)
A language that doesn't affect the way you think about programming is not worth knowing.

The Math object has a method round()which will do this for you eg.
var test = 12.3;
offset = Math.round(test);
Response.Write(offset);

If you are using JScript, but I like it A language that doesn't affect the way you think about programming is not worth knowing.

How about

Dim var, str
str = 123.32
var = cint(str)

Thanks,

Also consider Math.floor() if you are using JScript. Math.round() rounds the number:

2.4 ==> 2
2.5 ==> 3
2.6 ==> 3

whereas Math.floor() truncates the decimal, effectively forcing a round down

2.4 ==> 2
2.5 ==> 2
2.6 ==> 2

The vbscript function fix will remove any decimal value from the number.
The differance between using fix and using cInt or Round is that fix doesn't round at all, it only removes decimals from an number:

Number cInt	Round	Fix
5.333	5	5	5
5.8	6	6	5
-5.333	-5	-5	-5
-5.8	-6	-6	-5

If you really only want the base integer of the number, without rounding, use fix, if you want the closest integer representation (rounding) use cInt or Round.

hmm, repost to look more readable:

Number   cInt   Round   Fix
5.333     5       5      5
5.8       6       6      5
-5.333   -5      -5     -5
-5.8     -6      -6     -5

That might make a little more sense --- --- --- --- --- --- --- --- --- --- --- --- --- --- --- --- --- ---

very nice Tarwn. I think out of all of us you get the star on this one. A language that doesn't affect the way you think about programming is not worth knowing.

"Fix" was the fix. Very much appreciated. Thank you, Tarwn... xjs
