Clues

  • a number is too large too be represented in the bits available (8)
  • Loss of value by rounding a number to the nearest value that may be stored (8)
  • The relative error identifies the scale of an ABSOLUTE error is measures by dividing the absolute error by the actual value (24/474) then times by 100 to form a percentage (24/474 x100) (8)
  • This happens when a number is too small to represented in the available number of bits. This would mean the number is close to Zero (9)
  • This happens when when you attempt to add or subtract numbers of very different sizes, this means subtracting a very very samll number from a large number will have an end result of nothing changing. (12)
  • This is the difference between the ACTUAL number and the NEAREST value that can be represented (8)
  • When the number of bits used to represent the mantissa is too small. (9)
