Convert an integer to a hexadecimal string (Float class)
The IntegerToHex intrinsic function converts an integer to its hexadecimal string representation. Only integers that convert to four hex bytes or less (so a maximum output string length of eight) are allowed.
Syntax
%string = float:IntegerToHex( number, [Signed= boolean])
Syntax terms
%string | A string variable to receive the converted value of the method object: float. |
---|---|
float | An integer value. The number must be convertible to a hex string that does not exceed the output size specified by the number value (plus a sign bit, if that is indicated).
If number is a negative value, you must specify |
number | A non-zero numeric value that specifies the number of bytes to be returned in hexadecimal format (two characters for each byte). The value must not be greater than 4. |
Signed | This is an optional, name required, Boolean value that indicates whether the method object number is to be converted to signed output or not. If Signed=True , the resulting hex string will begin with a sign bit '00 ' or 'FF '), and a two's complement conversion is performed.
Signed defaults to False, which produces an unsigned conversion. |
Usage notes
- If the specified size of the returned hex value is greater than the hex value, the returned value is padded on the left with repetitions of the appropriate sign bit.
- If the specified size of the returned hex value is insufficient to contain the converted value and any necessary sign bit, the request is cancelled.
- IntegerToHex is available as of Sirius Mods Version 7.5.
Examples
- The following statement displays
00000000
:printText {0:integerToHex(4)}
- The following statement displays
0000000A
:printText {10:integerToHex(4)}
- The following statement displays
FF
:printText {255:integerToHex(1)}
- The following statement displays
FF
:printText {-1:integerToHex(1, signed=true)}
See also
- The inverse of the IntegerToHex method is HexToInteger.
