Afternoon all,
This is a quick survey, think it would be useful to have the values of
MAX_FLOAT for each platform, and indeed see if it does differ.
to do this can you please run the following code (bc* required) and
reply back with the output (and your platform / php version)
code:
<?php
function getMaxFloat() {
$value = '1';
$multiplier = '1';
while(1) {
$value = bcadd( $value , $multiplier );
if( (float)$value == INF ) {
$value = $oldvalue;
$multiplier = '1';
} elseif( ((float)bcadd( $value , '10' )) == INF ) {
while(1) {
$value = bcadd( $value , '1' );
if( (float)$value == INF ) {
return $oldvalue;
}
$oldvalue = $value;
}
}
$oldvalue = $value;
$multiplier = bcmul( $multiplier , '10' );
}
}
define( 'FLOAT_MAX' , getMaxFloat() );
echo FLOAT_MAX . PHP_EOL;
?>
my results:
Win Vista 32 bit on Intel Quad Core Duo - PHP 5.2.8
