Using Java’s Float class. float f = Float.parseFloat(“25”);
String s = Float.toString(25.0f);
To compare it’s always better to convert the string to float and compare as two floats. This is because for one float number there are multiple string representations, which are different when compared as strings (e.g. “25” != “25.0” != “25.00” etc.)Best answer · 354
Float to string – String.valueOf() float amount=100.00f;
String strAmount=String.valueOf(amount);
// or Float.toString(float)
String to Float – Float.parseFloat() String strAmount=”100.20″;
float amount=Float.parseFloat(strAmount)
// or Float.valueOf(string)31
You can try this sample of code: public class StringToFloat

public static void main (String[] args)

// String s = “fred”; // do this if you want an exception

String s = “100.00”;

float f = Float.valueOf(s.trim()).floatValue();
System.out.println(“float f = ” + f);
catch (NumberFormatException nfe)
System.out.println(“NumberFormatException: ” + nfe.getMessage());

I believe the following code will help: float f1 = 1.23f;
String f1Str = Float.toString(f1);
float f2 = Float.parseFloat(f1Str);4
This is a possible answer, this will also give the precise data, just need to change the decimal point in the required form.
public class TestStandAlone {

* This method is to main
* @param args void
public static void main(String[] args) {
// TODO Auto-generated method stub
try {
Float f1=152.32f;
BigDecimal roundfinalPrice = new BigDecimal(f1.floatValue()).setScale(2,BigDecimal.ROUND_HALF_UP);

System.out.println(“f1 –> “+f1);
String s1=roundfinalPrice.toPlainString();
System.out.println(“s1 “+s1);
} catch (Exception e) {
// TODO Auto-generated catch block

Output will be
f1 –> 152.32
s1 152.322
well this method is not a good one, but easy and not suggested. Maybe i should say this is the least effective method and the worse coding practice but, fun to use, float val=10.0;
String str=val+””;
the empty quotes, add a null string to the variable str, upcasting ‘val’ to the string type.1
String str = “1234.56”;
float num = 0.0f;

int digits = str.length()- str.indexOf(‘.’) – 1;

float factor = 1f;

for(int i=0;i=0;i–){

if(str.charAt(i) == ‘.’){
factor = 1;
System.out.println(“Reset, value=”+num);

num += (str.charAt(i) – ‘0’) * factor;
factor *= 10;

How do you convert a float to string (SOLVED) – Arduino Forum

Jun 02, 2014 · A String is not a string. A String is an object supported by the String library.

Using them does not fragment memory because they are not continually created and destroyed.
