Further Exponents
If you want to use very large or very small numbers in calculations, it is sometimes
useful to use scientific notation. The letter E is used for the exponent of numbers to
the base 10. You may use either lower case e or upper case
E.
For example 300 is the same as 3xl02. In scientific notation, this is 3
E 2.
Similarly,
0.03 is the same as 3x10- 2 . In scientific notation this is 3
E - 2.
Try the following
examples.
You can type in:
? 30* 10
[RETURN]
300
or you can type:
?
3 E 1

1E 1 [RETURN]
300
?3000*f000 [RETURN] ....
or.-...
?3E3*1 E3 [RETURN]
3000000
?3000*0.001
[RETURN] .... or ....
?3E3*1E-3
