NOTES:
Some of the number class uses the system functions strtol(), strtoll()...
To avoid patching the end \0 or copying the buffer unnecessary, all calls
to system functions are wrapped to a String object that adds the end null
if it only if it isn't there.
This adds some overhead when assigning numbers from strings but makes
everything simpler.
