FDec( <expression> )
Contents |
Description
Returns a float representation of a hexadecimal string.
Parameters
expression
The hexadecimal string to convert.
Return Value
Success: Returns a float.
Failure: Returns 0.
Remarks
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
