This 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.

The IntegerToHex function is available as of version 7.5 of the Sirius Mods.

IntegerToHex syntax

  %str = number:IntegerToHex(num, [Signed=bool])

Syntax terms

%str
A string variable to receive the converted value of the method object number.
number
An integer value. The number must be convertible to a hex string that does not exceed the output size specified by the num value (plus a sign bit, if that is indicated). If number is a negative value, you must specify 'Signed=true'.
num
A non-zero numeric value that specifies the number of hex bytes to be returned. Its value must be greater than 0 and less than 5.
Signed=bool
This name-required argument ('Signed') is a boolean value that indicates whether the method object number is to be converted to signed output. If so, the resulting hex string will begin with a sign bit '00' or 'FF'), and a two's complement conversion is performed. Signed is an optional argument that 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.
  • The inverse of the IntegerToHex method is HexToInteger.

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)}
