Convert float to String in blackberry

Hi

   I need to set the string value to the editfied. So I want to convert  the float value (with exponent) to string. 

 

So i used Formatter api to handle the exponent and convert to string by the following code.

 

Formatter formatter = new Formatter("en"); 
textBox.setText(formatter.formatNumber(floatValue, 2));

 

But in my requirement i need to pass '0' as decimal value. So when i pass the the decimal value as '0', then the applicaiton is crashing again (illegalargument exception).  Because formatter accepts decimal value as 1 to 15 and not as '0'. But i want to use '0' as decimal value. 

 

Can anybody let me know that anyother way to solve this issue?

 

Thanks

mindus

Re: Convert float to String in blackberry

I don't understand the requirement to pass '0' as decimal value.
parameter:
decimals - the number of decimals to use

getting a result with 0 decimals makes no sense as it would be empty.

Pass 1 and remove the last 2 characters?

double value = 0.0;
Formatter fmt = new Formatter("en");
System.out.println(fmt.formatNumber(value, 2));

 

 

you will get   0.00 as a String
