Hi. I was wondering why when I add 2 number objects together I get them returned combined rather than summed together.

The following returns 0.000.25 rather than 0.25

Can anybody enlighten me as to what is going on?

Like so:

a = new Number(0.0);
b = new Number(0.25);
c = a.toFixed(2);
d = b.toFixed(2);
return c + d;

This doesn't happen when subtracting.

O.k so i figured out that It's returning a string concatenation of the two values. The + operator is also used for string concatenation so JS gets confused. subtracting 0 from both values makes sure JS knows that it is dealing with numbers.

(c-0)+(d-0) returns an accurate result.


As the toFixed() method converts from a number to a string you could always use parseFloat() to turn it back into a number. This is essentially what subtracting 0 is doing.
