I'm trying to add two values together e.g. 14.0 + 2.1 = 16.1 but I keep on getting them added onto each other e.g 14.0 + 2.1 = 14.02.1
var miledistance = miledistance1 + miledistance2;

Perhaps you are using Javascript which is not the same as Java.Peter Lawrey– Peter Lawrey2011-06-22 15:02:35 +00:00Commented Jun 22, 2011 at 15:02

For Java:
Make sure they are both float values.
Try casting:
miledistance = (float) miledistance1 + (float) miledistance2;
Or use Float.valueOf():
miledistance = Float.valueOf(miledistance1) + Float.valueOf(miledistance2);
For Javascript:
miledistance = parseFloat(miledistance1) + parseFloat(miledistance2);
NOTE: Java and javascript are not the same language.

OPs problem looks like string concatenation; could you change the Java example to something parsing the string (say,
Float.valueOf(...) instead of the cast)?It seems to be that the program is treating them as strings, cast them as float or double.
