Write down all six numbers as both signed and unsigned decimal values. t.. a. /‹... _^s.. 3. t... A‹"u... 6......... 10 Stored numbers, integers Six numbers are stored in the first 12 bytes of a file. It is known that they are 16-bit little endian values but it is not known if they are signed or unsigned. Write down all six numbers as both signed and unsigned decimal values. t.. a. /‹... _^s.. 3. t... A‹"u... 6......... Enrichment Concepts of data storage: floating point type Floating point numbers are very useful for the convenient representation of fractions but they are not always accurate.
This means that each pixel is stored in 1 byte in the file so there are 54 ϫ 76 ϭ 4104 pixels in the whole image. The file is 5334 bytes in size, the rest of the 5334 Ϫ 4104 bytes of data are stored in a ‘file header’ and contains mainly a ‘colour palette’, a means to specify which colours are to be used. A typical system will use 3 bytes to store each pixel, one for the red intensity, one for green and one for blue. 7 million. In an image like this one that can store only 256 colours per pixel, each pixel is represented by 1 byte and the ‘palette’ holds 256 entries, each of the 256 entries holds a 3-byte colour.
5703125 to a fixed point binary fraction. 1001001 reading from the top Use a spreadsheet to do the conversions of the following numbers: • to at least 60 binary places; • if the numbers were then to be used in a floating point number with a 48-bit mantissa, show which of the numbers would cause a slight inaccuracy. 141592654 1-26 60 place binary 48-bit accurate? 12 Number bases Fill in the spaces in the table by converting number bases as required. Hints: • Binary to hex or hex to binary, use groups of four binary digits.
