Convert an integer to a binary string (Float class)
The IntegerToBinary intrinsic function converts an integer to its binary string representation. Only integers that convert to a string no longer than four characters are allowed.
Syntax
%string = float:IntegerToBinary( 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 binary string that does not exceed the length specified by the number value. |
| number | A non-zero numeric value that specifies the length in bytes of the binary string to be returned. Its value must be greater than 0 and less than 5. |
| Signed | This is an optional, name required, Boolean enumeration that indicates whether the method object integer is to be converted to a signed integer. If so, the resulting binary string will begin with a sign bit, 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 length of the returned binary string is greater than the binary value, the value is padded on the left with repetitions of the appropriate sign bit.
- If the specified length of the returned binary string is insufficient to contain the converted value and any necessary sign bit, the request is cancelled.
- IntegerToBinary is available as of Sirius Mods Version 7.3.
Examples
- The following statement displays an '
a' character:printText {129:integerToBinary(1)}
- The following statement displays '
??' because the resulting binary string is two non-displayable characters:printText {32769:integerToBinary(2)}
- To view the hex equivalents of the non-displayable characters in examples above, you can use StringToHex. The following statement The displays '
8001'.printText {32769:integerToBinary(2):stringToHex}
- The following statement displays '
FF7F':printText {-129:integerToBinary(2, signed=true):stringToHex}
- The following statement displays '
0081, a value padded with a positive sign bit:printText {129:integerToBinary(2, signed=true):stringToHex}
