DHex( <expression> )
Contents |
Description
Returns a string representation of an double type converted to hexadecimal
Parameters
expression
The expression to convert.
Return Value
Success: Returns a string of length characters, zero-padded if necessary for integer.
Failure: Returns "" (blank string).
Remarks
The function only works with numbers that fit in a 64 bit signed floating point.
It is best to cast numbers with (double) to make sure its going to be a double.
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
