12 ** Integer formats used in the printf family of functions now work for
13 64-bit integers and are more compatible with Matlab when printing
14 non-integer values. Now instead of truncating, Octave will switch
15 the effective format to '%g' in the following circumstances:
16
17 * the value of an integer type (int8, uint32, etc.) value exceeds
18 the maximum for the format specifier. For '%d', the limit is
19 intmax ('int64') and for '%u' it is intmax ('uint64').
20
21 * round(x) != x or the value is outside the range allowed by the
22 integer format specifier.
23
24 There is still one difference: Matlab switches to '%e' and Octave
25 is currently switching to '%g'.
