Hex( <expression>, <length> )
Contents |
Description
Returns a string representation of an integer type converted to hexadecimal.
Parameters
expression
The expression to convert.
length
Optional; Number of characters to be returned (up to 16) for (64-bit) integer. Characters are truncated from the left-hand side if length is too small.
If this is -1 then it will return the hex with no leading zeros (unless of course the value converts to something like 01EB)
Default: -1
Return Value
Success: Returns a string of length characters, zero-padded if necessary for integer.
Failure: Returns "" (blank string).
Remarks
The function works with numbers that fit in a 32 bit signed integer OR 64 bit signed integer.
It is best to cast numbers with (int) to make sure its going to be a int.
Example
$result = Hex(1033); println($result); // prints "409" $result = Hex(1033, 4); println($result); // prints "0409" $result = Hex(1033, 8); println($result); // prints "00000409"
Example with cast on a $variable
$var = 1033; $result = Hex((int)$var); println($result); // prints "409" $result = Hex((int)$var, 4); println($result); // prints "0409" $result = Hex((int)$var, 8); println($result); // prints "00000409"
