Test script: --------------- var_dump(bccomp(-INF, 1.0, 2)); Expected result: ---------------- No warning Actual result: -------------- PHP Warning: bccomp(): bcmath function argument is not well-formed ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=80867&edit=1
