not getting exact answer when adding floating numbers.

[shiniskumar]

Ive got to sum up 5 numbers.
125000+23500.75 +5525725.79+325 7500+63542.36
When summing these i should get the answer as 8995268.9
but im getting the answer as 8995268.899999

My script code is as follows
------------------------------------------
var totalDebit =0;
(here dtAmt[i] contains each of the above specified numbers)
for(i=0;i<5;i++ ){
if(!isEmpty(dtA mt[i].value)){
totalDebit =parseFloat(tot alDebit) +parseFloat(dtA mt[i].value);
}
}

Y do i get the anonymous answer.?

I will move this to the Javascript forum where it belongs and where you are likey to be told about how parseFloat approximates values ...

After calcualtion add the following formatting (to get 2 decimals):

totalDebit = totalDebit.toFixed(2);

It seem that only works in IE 5.5+ and Netscape 6+.

Use

totalDebit.toFixed(1);

to round to one decimal place and yes, parseFloat is only approximate.

Ah, so this was double posted!

not getting exact answer when adding floating numbers.

when i add 1125345.55+1056 87.69+178954.89 +86933.72

i should get the answer as 2172811.85 but i get the answer as 2172811.84999

the code is as
where dtAmt[i] consists of the numbers

var floatSum=0;
var intSum=0;
for(i=0;i<openi ngLedger1.lengt h;i++){

if(!isEmpty(dtA mt[i].value)){
var amnt=dtAmt[i].value;
if(!isInteger(d tAmt[i].value)){
floatSum=parseF loat(floatSum)+ parseFloat(amnt );
}
else{
intSum=parseFlo at(intSum)+pars eFloat(amnt);
}
totalDebit =parseFloat(flo atSum) +parseFloat(int Sum);
}
