In-Depth Information
The integer literal suffixes are listed in Table 8-1. For a given suffix, the compiler will inter-
pret the string of digits as the smallest of the corresponding integer types that can represent the
value without losing data.
For example, take the literals
236
and
5000000000
, where neither of them has a suffix. Since
236
can be represented with 32 bits, it will be interpreted by the compiler as an
int
. The larger
number, however, will not fit into 32 bits, so it is interpreted as a
long
.
