Engineering Notation

Engineering notation is a method of notation that specifies that all powers of ten used to define a number must be 0 or multipliers (multiples) of 3 with a mantissa must be greater than or equal to 1 but less than 1000. 

Engineering notation makes use of powers of ten, with restrictions on the mantissa (multiplier) or scale factor (power of ten).



Example:
a. Using engineering notation in the floating-point mode
1/3         = 333.333333333E-3
1/16       = 62.5E-3
2300/2 = 1.15E3

b. Using engineering notation with two-place accuracy (fixed-point mode)

1/3         = 333.33E-3
1/16       = 62.50E-3
2300/2 = 1.15E3
