float validation

[rtnMichael]

Hey guys, is it any different to validate floats as it is to validate integers? I have a form with three text boxes: upper and lower specs and an input box for a user input value. For example, an upper is 1.2345 and a lower is 1.0293. I want to check to see if the value input is between the two specs. Would it be any different to check against these values because they're floats?

Thanks
Mike

Here's what I have, don't know if it's right....well, can actually say it doesn't work right, I don't get the desired Pass/Fail I want.

function figurepassfail(ValueArr, Value_LowerArr, Value_UpperArr, max_parms)
{
var j = 0;
var flag;
PassFailArr = new Array();

while(j < max_parms)
{
flag = true;

if(!ValueArr[j])
{
}

else
{
//just to test if the uppers and lowers exist
if(Value_UpperArr[j] && Value_LowerArr[j])
{
if((ValueArr[j] > Value_UpperArr[j]) || (ValueArr[j] < Value_LowerArr[j]))
{
flag = false;
PassFailArr[j] = &quot;Fail&quot;;
}

else PassFailArr[j] = &quot;Pass&quot;;

}

else if(Value_UpperArr[j] && !Value_LowerArr[j])
{
if(ValueArr[j] > Value_UpperArr[j])
{
flag = false;
PassFailArr[j] = &quot;Fail&quot;;
}

else PassFailArr[j] = &quot;Pass&quot;;

}

else if(Value_LowerArr[j] && !Value_UpperArr[j])
{
if(ValueArr[j] < Value_LowerArr[j])
{
flag = false;
PassFailArr[j] = &quot;Fail&quot;;
}

else PassFailArr[j] = &quot;Pass&quot;;

}
}
j = j + 1;
}

document.form3.PassFail_str.value = PassFailArr;
return flag;
}

Why is this so complex? Am I missing something?

function checkNum(){
upperNum = document.myForm.upperNum.value
lowerNum = document.myForm.lowerNum.value
midNum = document.myForm.midNum.value
if (!isNaN(upperNum) && !isNaN(lowerNum) && !isNaN(midNum){
if (parseFloat(lowerNum) < parseFloat(midNum) && parseFloat(midNum) < parseFloat(upperNum)){
alert(&quot;all good&quot
}
else{
alert(&quot;No good&quot
}
}
else{
alert(&quot;Bad Data&quot
}
}

ok, quick question, I see that isNaN doesn't care if the values are not there. What do I do if the value isn't entered?

if (!isNaN(upperNum) && !isNaN(lowerNum) && !isNaN(midNum) && upperNum != &quot;&quot; && lowerNum != &quot;&quot; && midNum != &quot;&quot; ){

yeah, see I have been having a bad 2 weeks, you would think I would have thought of something so obvious!!!!

Thanks for all the help
