fixes #4966
The removed code is residual from 136fae3 and even a difference by
PHP_FLOAT_EPSILON
should be reported as a failure.The
PHP_FLOAT_EPSILON
constant equals to2.220446049250313E-16
(see 3v4l link in a post below) and is usable only when theabs(a - b)
is done on normalized values, but when done so, the comparison is useless or satisfied because of the normalization rounding error solely. On the other side, imagine comparing very small numbers like1e-100
and1e-200
. The difference between these two normalized values is astronomically large, but currently the phpunit handles such numbers as same!
