DDec( <expression> )
Contents |
Description
Returns a double representation of a hexadecimal string.
Parameters
expression
The hexadecimal string to convert.
Return Value
Success: Returns a double.
Failure: Returns 0.
Remarks
The function only works with numbers that fit in a 64 bit signed floating point.
Example
$lol1 = (double)1337.77; $fDHex = DHex($lol1); $fDDec = DDec($fDHex); println( "DOUBLE HEX: " . $fDHex ); // Prints 4094E7147AE147AE println( "DOUBLE DEC: " . $fDDec ); // Prints 1337.77
Example with cast on a $variable
$var = 1337.77; $fDHex = DHex((double)$var); $fDDec = DDec($fDHex); println( "DOUBLE HEX: " . $fDHex ); // Prints 4094E7147AE147AE println( "DOUBLE DEC: " . $fDDec ); // Prints 1337.77
