Numbers in Javascript have 64 bits :
- 1 bit for the sign (+ or -)
- 11 bits to store the location of the point in the number
- 52 bits for the number itself
2^52 = 4 503 599 627 370 496 (~ 4.5x10^15), so if you assign numbers greater than 2^52, results are uncertain up to ~ 10^308 (it's infinite over).
If you don't need to do operations on these big numbers, using strings is indeed a good solution.
See this MDN article about Number type and ECMAScript standard page for more information.
