Question

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;

Answer 1

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.
