Bug description: Wrong conversion of float to string
Description:
------------
Some float numbers are incorrectly converted to string values:
I found it by playing with eval and getting wrong results. Then I did:
echo floatval('3.86e-6'); // output: 3.86E-6
echo floatval('1.01e-6'); // output: 1.01E-6
But
echo floatval('1E-6'); // output: :.0E-7
But one can do:
$f=1E-6;
echo $f; // output: .0E-7
So it must be a problem with float to string conversion.
Reproduce code:
---------------
$f=1E-6;
echo $f; // output: :.0E-7
Expected result:
----------------
1.0E-6
Actual result:
--------------
:.0E-7
