Common function menu (B) [B NUM]:
• Check the menu. Press
≥
B
to display the
screen shown on the right.
• There are a total of nine options in the NUM menu.
(See the list in APPENDIX “6. Explanation of EL-
9650 menus” for the explanation of functions on
page 287.)
• The menu includes functions that return absolute
value [abs( ], rounded number [round( ], integer part
[ipart], [int], fractional part [fpart], minimum and
maximum values [min(], [max( ], least common
multiple [lcm( ] and greatest common divisor [gcd( ].
