IntegerToHex (Float function)
Convert an integer to a hexadecimal string (Float class)
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.
Syntax
%string = float:IntegerToHex( number, [Signed= boolean])
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)}
