This isn't true. %g often uses scientific notation even though it'd be shorter not to, and what's more, its output may differ from BOTH %e and %f, since it strips trailing zeros and %f and %e don't. See https://stackoverflow.com/q/54162152/1709587 where I explore this point at length. ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=77451&edit=1
