FHex( <expression> )
Contents |
Description
Returns a string representation of an float 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 32 bit signed floating point.
It is best to cast numbers with (float) to make sure its going to be a float.
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
