You can choose between 2 different types of.exponential display formats. Norm 1:10-2(0:01)> 'xi , Ixl Norm 2:10-°(0.000000001)> I x I , I L-101° - Use either of the following procedures to switch between the two exponential display for- mats between Norm 1 and Norm 2. •In the COMP Mode, press El(SET) or Mill= for the set up edit display. Next, press a C)CCI(Nrrn). i- •Press L1151 to display the display format menu. Next,,press (Nrm)R. Pressing Euro displays the current mode settings CD11:1200g /1+200 , 5 .

This means that you should move the decimal point in 1.2 twelve places to the right, since the exponent is positive. This results in the value 1,200,000,000,000. 1.2E-3 1.2E I II -03 I Mantissa Exponent 1.2E-03 indicates that the result is equivalent to 1.2 x 10-s.
