If you're thinking of the "precision" setting, it doesn't do anything nearly that clever; it's purely about how many decimal digits should be *displayed* when converting a binary float value to a decimal string. In recent versions og PHP, it has a "-1" setting that automatically does the right thing in most cases. https://www.php.net/manual/en/ini.core.php#ini.precision The other way around - parsing a string to a float, including when compiling source code - has a lot of different compile-time options, presumably to optimise on different platforms; but no user options at all: https://github.com/php/php-src/blob/master/Zend/zend_strtod.c Regards, -- Rowan Tommins [IMSoP]
