Round a number

Hello. Again i'm here to make some questions.

 

I'm building an URL to send it ro Google Chart API and it will return an image.

 

What i need to do is get the maximum value of the Chart data and round up it to An integer...

For example...

 

If my maximum value is 2475.59 i want to convert it to a string and round up to 2500.

 

Can i do it?

 

Anyone can help me?

 

Tks

You'll need to figure out how much you want to round to, and then do the appropriate math. In your example, you might do:

 

 

String roundedValue = String.valueOf(Math.round(preValue/100)*100);

This would convert 2475.59 to 24.7559, then rounded to 25.0000, then multiplied back, becomes 2500.00. From there, String.valueOf takes care of the conversion from a number to a string value.
