For question 2., if it's a binary file,freadcan read the data as signed integer as is. Use: out = fread(fid, numvalues, *int16); If it's a text file, convert your hexadecimal string with: out = typecast(uint16(
Number representation techniqueslike:Binary,Octal,Decimal, andHexadecimalnumber representation techniques can represent numbers in both signed and unsigned ways. Binary Number System is one the type of Number Representation techniques. It is most popular and used in digital systems. Binary system is used...

does the binary math and sets the flags appropriately. It's up to you, the programmer, to know which flag to check after the math is done. If your program treats the bits in a word as unsigned numbers, you must watch to see if your arithmetic sets the carry flag on, indicating ...

signature = hash(SigningKey, string-to-sign) Convert the signature from binary to hexadecimal representation, in lowercase characters.To calculate a signature for SigV4a Using the digital signing algorithm (ECDSA P-256), sign the string to sign you created in the previous step. The key used fo...
Computer people began using hexadecimal and octal numbers for one main reason: computers think in binary and human beings have a hard time reading long binary numbers. For people, it’s much easier to convert binary to hexadecimal than binary to decimal, because sixteen is an even power of tw...
xxd -ps signed-tcl-file > nonbinary-signature-file This command converts the signature in signed-tcl-file from binary to nonbinary data and stores it as a hexadecimal dump in the file nonbinary-signature-file. Example: Host% xxd -ps hello.pk7 > hello.hex Step 2...
