Found a VERY interesting usage for the number format system.
If the function microtime(TRUE) is called, i.e. return unix timestamp with the microseconds, you get
2 to 4 places after the decimal place for some weird reason. You'd think that you'd get
all of them.
You can recover all the decimal places two ways:
(1)
$reversedMantissaStringWithSpaceAsSeparator = microtime();
$mantissaAndRootInArray = explode( " ", $reversedMantissaStringWithSpaceAsSeparator );
$timestampWithMostOrAllDecimalPlaces = ( $mantissaAndRootInArray[1] . $mantissaAndRootInArray[0] );
echo $timestampWithMostOrAllDecimalPlaces;
or by using number_format, which I think returns a LOT MORE PLACES for some reason:
(2)
echo number_format( microtime(TRUE), 100)."<br>";
//note I get 22 places after the decimal, even MORE than the string version shows.
I have NOOOOOOO idea how accurate that is LOL! Or what's going on either. Just interesting.
