I've always (20+ years) known that Javascript numbers were floats, I've thus always assumed JSON numbers to be as well. Is this not the spec? I just store big i

I've always (20+ years) known that Javascript numbers were floats, I've thus always assumed JSON numbers to be as well. Is this not the spec? I just store big integers in JSON strings.

JSON numbers are arbitrary precision, because the spec doesn't limit the precision in any way.

  You are right, but as theamk pointed out in another comment, the spec does tell you to "expect no more precision or range than" IEEE754 doubles. So, don't count on arbitrary precision...
