¢@ Function Keys
One of the features of this computer permits
one-key input of functions as in scientific ca

an exponential function (10*) based on. 10.
When these keys are pressed after the = key,

Functions of Components
© Hexadecimal Key ( ''&§)
Press (#4) hexadecimal number &, and a hexadecimal number will be converted
into a decimal number. Press @4'@4 decimal number OG) &4, and a decimal number
will be converted into a 4-digit hexadecimal number.
© Engineering Key ( Ge )
When this key is pressed, a calculation result or a numeric value displayed by a
PRINT
statement is converted into an exponent display. When this key is
pressed repeatedly, the displayed exponent will decrease by 3 each time. The
Al =
eS.
exponent can be increased by 3 each time by pressing &
(Multiple of 3: 10° = K (kilo), 10° = M (mega), 10° = G (giga), 10°° =m
(milli), 10°° = # (micro), 10 = n (nano), 10°!? = P (pico)
@ Replay/Answer key ( (ae) )
Press this key to recall the last input contents calculated using &§. When this key
is pressed after pressing the FJ key, the last calculated result can be recalled.
© Statistical Data Input Key ( @5 )
Press this key after statistical data, and the data will be input to an exclusive
memory
area. When pressed following the
J key, an SDEL function is per-
formed to delete the input statistical data from the memory area. (For details,
see page 33.)
'
@ Function Memory Keys ( [)(ou}taiq)
These keys are for the Function Memory. They will be described in detail in
Chapter 3.
© Cursor Movement Keys ( 23285 )
These keys are used when correcting displayed characters. The cursor (""_" blink-
ing in the display window) is moved right and left by these keys. Each time this
key is pressed, the cursor moves by. one character. When the key is held down,
the cursor moves continuously through all of the characters present. When
US is pressed, the cursor moves to the left edge of the display (the beginning
of the line) — LINE TOP function. When @jH# is pressed, the cursor moves to
the right of the last input character (the end of the line) - LINE END function.
