How to convert string to double?
Ive got a double variable dTot;
its value is 5.037717235E7
when i did FreemarkerTools .formatDecimal( dTot) i got it as string "50377172.3 5".
now i want to pass it as a double value to the method format() which is shown below.
when i do Double.parseDou ble i get dTot as 5.037717235E7
CurrencyConvert er.format(Doubl e.parseDouble(F reemarkerTools. formatDecimal(d Tot)));
what else can i do to pass it as 50377172.35 to the method format()
public class CurrencyConvert er {
public static String format(double n) {
if(n<0)
return "("+formatAcc(M ath.abs(n))+")" ;
return formatAcc(n);
}
public static String formatAcc(doubl e n){
//long decPart=0;
String s1 = ""+n;
String[] nums = s1.split("\\.") ;
long decPart = Integer.parseIn t(nums[1]);
// long decPart = (long) ((n-Math.floor(n))* 100);
if(n==0)
return "0.00";
int arr[] = new int[] { 1000, 100, 100, 100, 100, 100 };
String arrFromat[] = new String[] { "000", "00", "00", "00", "00",
"00" };
String s = "";
for (int i = 0; i < arr.length; i++) {
long x = (long) (n % arr[i]);
if (s.length() > 0)
s = "," + s;
n = n / arr[i];
if (n < 1) {
s = x + s;
break;
} else {
s = format(x, arrFromat[i]) + s;
}
}
return s+"."+format(de cPart,"00");
}
private static String format(long n, String format) {
String temp = n + "";
temp = format.substrin g(temp.length() ) + temp;
return temp;
}
public static void main(String[] args) {
System.out.prin tln(CurrencyCon verter.format(5 54406000.40));
}
}

Use it like that for calculations. You will get the correct result.
Which calculation are you getting problems with it?
after splitting i get the decimal part as 355434664e7
when taking parseInt() of this i get error
long decPart = Integer.parseIn t(nums[1]);

Do not split the double, split the String.
Now look here my friend.
You have your number as a string as "55440600.4 0".
Pass it to the function like that as a String. So your function becomes - public void myFunction(String value) {
-
//Now split the String value
-
String[] values = value.split("\\.");
-
//Then do your parseLong or parseInt on the values of the array
-
//If you need to do calculations using the value, then change it to
-
//double using parseDouble
-
Now where do you not understand?

got it correctly when i did parseLong instead of parseInt.
Thankyou very much

You really should start your thread for that.

Hi,
I have this number, 1.5283632704970307 in char*, and I need to convert
it to a double type in C++ that is capable of storing that number of
precisions.... I tried doing atof and storing it to a double type. it
came back with 6 digits precision only.
I also have this number, 1159964886109, in char*, and I need to convert
it to uint64... i did a atol, it converted it to a 2147483647, which
truncated 4 bytes for me...

How do you convert a hex string into a double using C# in framework v2.0?
I've seen this question answered before, but apparently something has
changed in 2.0 that negates the old solution that I've seen. The code:
DoubleVariable = Double.Parse(HexString, NumberStyles.AllowHexSpecifier);
results in the error:
"The number style AllowHexSpecifier is not supported on floating point data
