Can you post the same here? ------------------------------------------------------------------------ [2008-05-28 13:24:21] rudolphi at chemie dot uni-kl dot de Description: ------------ When converting a number in exponential format with negative exponent of n=6,7,... strval (or implicit conversion to string) gives :.0E-(n+1) if there is no fractional part present. The error can be found both in the precompiled PHP 5.2.4 and self-compiled 5.2.6, but it cannot be reproduced under Windows or under PHP 5.2.3 Ubuntu 7.10 (64bit). Seems to be closely related to OS (?). Reproduce code: --------------- $float=1e-6; echo strval($float); Expected result: ---------------- 1e-6 or 1.0e-6 Actual result: -------------- :.0E-7 ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=45117&edit=1
