Return Value

The function only works with numbers that fit in a 32 bit signed floating point.
Example
$lol = (float)1337.42 $fHex = fHex($lol) $fDec = fDec($fHex) println( "FLOAT HEX: " . $fHex ) ; Prints 44A72D71 println( "FLOAT DEC: " . $fDec ) ; Prints 1337.42004394531
Example with cast on a $variable
$var = 1337.77 $fHex = fHex((float)$var) $fDec = fDec($fHex) println( "FLOAT HEX: " . $fHex ) ; Prints 44A72D71 println( "FLOAT DEC: " . $fDec ) ; Prints 1337.42004394531
