So it can exactly represent integers up to 2^52, @Karl: The decimal fraction 1/10 cannot be represented as a finite binary fraction in base 2, and that's what Javascript numbers are. Then, as far as I understand, we can round the value up to 15 digits to keep a nice string representation. As seen in the above output we can find the real and imaginary part of the complex number and convert it from rectangular to polar and vice versa. Numerical libraries which present results that look clean simply cut off the last 2 digits at every step, numerical co-processors also have a "normal" and "full" lenght for the same reason. The recommended approach is to use correction factors (multiply by a suitable power of 10 so that the arithmetic happens between integers). "1120003000600.126" * 1 still comes out to 1120003000600.126 "11200030006000.126" * 1 still comes out to 1120003000600.127 which makes any solution painful, anything over 13 digits gets broken.
