___________________________________________________
(*) In the SI system, this prefix is da rather than D. Use D for deka in the
calculator, however.
To enter these prefixes, simply type the prefix using the ~ keyboard. For
example, to enter 123 pm (1 picometer), use:
123‚Ý~„p~„m
Using UBASE to convert to the default unit (1 m) results in:
Operations with units
Once a quantity accompanied with units is entered into the stack, it can be
used in operations similar to plain numbers, except that quantities with units
cannot be used as arguments of functions (say, SQ or SIN). Thus, attempting to
calculate LN(10_m) will produce an error message: Error: Bad Argument Type.
Here are some calculation examples using the ALG operating mode. Be
warned that, when multiplying or dividing quantities with units, you must
enclosed each quantity with its units between parentheses. Thus, to enter, for
example, the product 12.5m
× 5.2_yd, type it to read (12.5_m)*(5.2_yd) `:
