Primitive integer types have well-specified value ranges
byte [ -pow(2,7) , pow(2,7) )
short [ -pow(2,15) , pow(2,15) )
int [ -pow(2,31) , pow(2,31) )
long [ -pow(2,63) , pow(2,63) ) .
Primitive operations on these types wrap-around in case of overflow,
but there are methods which throws Arith
Correction.
The unrestricted BigInteger range is
( -pow(2, (pow(2,31) - 1)*32) , pow(2, (pow(2,31) - 1)*32) )
instead of
( -pow(2, pow(2,31) + 31) , pow(2, pow(2,31) + 31).
The restricted BigInteger range
[ -pow(2, pow(2,31) - 1), pow(2, pow(2,31) - 1) )
is ok.
