1. The Hex Calculator only functions with integral data types such as Short Long and Chars It does not function with Reals such as Floats or Doubles The Hex Converter can convert between Hex and Decimal or Decimal and Hex for all integral types but will only convert from Decimal to Hex for Real types Button Operations CLA Clears display to start new calculation Modulus operator Complement operator Exclusive OR operator amp Bitwise AND operator Bitwise OR operator lt lt Shift Left operator gt gt Shift Right operator Equal displays total or subtotal Mot Int switches between Big Endian Motorola or Raw data storage format and Little Endian Intel format Figure 2 5 Help Instructions 3 Error Messages Hexit has only one error message to alert the user when an input error occurs Figure 3 1 shows the error message This message is displayed whenever a hex calculation is attempted on a real data type 11 Must select Integral Data Type for this function EE Figure 3 1 Error Message 4 Product Test Information Hexit has been tested using a variety of test calculations These test calculations are designed to verify that Hexit performs calculations correctly It is impossible to build a list of test calculation to address every possible combination of functions and calculating conditions that can be encountered and so it is always possible that a calculation error may go undetected in testing Pleas2. lt lt 0 Ee Hes Converter HEX DECIMAL 295C8FC2F528F 4 1 26 BINARY 0010 1001 0101 1100 1000 1111 1100 0010 1111 0101 0010 1000 1111 0100 0011 1111 Double Data Type Figure 6 6 Double Format Conversion in Int Mode 1 2 3 Converting a Hexadecimal Number There are two ways to convert a Hexadecimal number to decimal and binary format The first way is to input the number into the Hexit HEX Calculator The HEX Converter automatically converts all numbers shown in the Hexit HEX Calculator Display The second way is to type a hexadecimal number into the Hexit HEX Converter s display 1 3 Hexit and Negative Numbers The following two rules apply to dealing with negative numbers when using Hexit e Hexit Hex Calculator performs bitwise operations the same for signed integers and unsigned integers e Signed integers are always input in hexadecimal format two s complement form Note there is no change sign button on the HEX Calculator To input a negative number the number must be input in its hexadecimal format Use the HEX Converter to get the hexadecimal format for a negative decimal number Remember to set the data type to a signed type char int or long when calculating with negative numbers 2 Menu Items Figure 2 1 shows the Hexit main menu which includes settings for Data Type View and Help File DataType View Help Figure 2 1 Hexit Menu Items 2 1 Data Type Figure 2 2 shows the settings for Data T
