Low level operations
Cards in this deck (8)
- 1what format do computers store all data inbinary (1 or 0)
- 2how are integers storedusing two's complement notation
- 3how do you convert binary to decimalwrite the binary number under its place values, then add them together
- 4how do you convert decimal to binaryrepeated division by 2 use the remainder to read upwards
- 5how do you convert a negative integer to a positive one using two's complimentwrite it as a positive binary number using the full bit length, invert it then add 1 real numbers are stored using floating point representation
- 6what is the mantissa and what does does it representthe mantissa determines the accuracy of the number in floating point notation
- 7what is the exponent and what does does it representthe exponent determines the range of numbers which can be stored in floating point notation
- 8increasing the number of bits in the mantissa...increases the precision of the number but decreases the range
