Storing in Variables

To store a
value
You can store numbers or expressions from any previous
input or result into variables.
A number stored
in a variable
is always stored as a 12-digit
mantissa with a 3-digit exponent. Numeric precision in the
display, however, depends on the display mode (Standard,
Fbced, Scientific, Engineering, or Fraction). A displayed
number has only the precision that is displayed.
