Question

I have several strings which contain numberic values.

I’d like to format these strings so that the numeric values have 1 or 2 decimal places.

Eg. One string might contain the value – “345.98765”

I’d like to format/change this so that there should only be 2 decimal places “345.99”.

Can this be done? I am not dealing with any double/float values, these numbers are pulled from XML files.

Thanks

You need to turn the Strings into numbers and then format them.

double d = Double.parseDouble(text);
String formatted = String.format("%.2f", d);
