![]() This is important if you want to prevent an unwanted stop during a program.Ģ9: If set the calculator separates digits in groups of three. The same as FC? and CF together.Ġ0–10 and 81–99: These 30 flags are not related to the calculators status but are just “binary memories” you can use for what you want.ġ1: When you turn on the calculator if the flag 11 is set the calculator runs the program where the “calculator's pointer” is stopped and clears the flag 11.Ģ4: If this flag is set the calculator will ignore error messages. True if the flag is set (true), and simultaneously clears the flag.įC?C: Flag clear test and clear. True if the flag is clear (false).įS?C: Flag set test and clear. True if the flag is set (true).įC?: Flag clear test. Makes a flag to be clear (false).įS?: Flag set test. ![]() Makes a flag to be set (true).ĬF: Clear flag. To work with flags there are some functions in the FLAGS menu (over the “6”) which are SF, CF, FS?, FC?, FS?C, FC?C (again the HP-42S has more functions than we need). Using flags you can get the status of the Me the most interesting reason is related to programming. Just for comparison the 33S has only 12 flags.īut why do we need flags? Why not set up the calculator status using just the default menus? For A flag can be “set” (true) or “clear” (false). A flag is a “binary memory” which works as an indicator Solution: In decimal mode enter 500 and then select HEXM. LOGIC: Show the logic functions AND, OR, XOR, NOT, BIT?, ROTXY.Įxample: How do we write 500 in hexadecimal mode? This menu has the following functions:Ī.F: Select hexadecimal mode and show A to F. It is a shame! Why not only two? :)ħ3: This flag if true makes the calculator to show complex numbers in polar notation.To work with other bases we must use the BASE menu (over the “4”). CCCC=Decimal (default), CCCS=Binary, CSSS=Octal and SSSS=Hexadecimal. If true the calculator does not turn off after about 10 minutes.Ħ8 to 71: Base modes. You cannot change the flags from 36 to 80.Ĥ4: Always on. FC?C: The same of FC? and CF together.Ġ0 to 10 and 81 to 99: These 30 flags are not related to the calculators status but are just “binary memories” you can use for what you want.ġ1: When you turn on the calculator if the flag 11 is set the calculator runs the program where the “calculator's pointer” is stopped and clears the flag 11.Ģ4: If this flag is set the calculator will ignorate error messages. Says if the flag is set(true) FC?: The same for clear(false) FS?C: The same of FS? and CF together. Makes a flag to be clear(false) FS?: Flag set test. (Again HP-42S has more functions than we need) To work with flags there are some functions in ▀ FLAGS menu (over the “6”) which are SF, CF, FS?, FC?, FS?C, FC?C. Using flags you can get the status of the calculator or change it from a program. Just for comparison 33S has only 12 flags.īut why do we need flags? Why not set up the calculator status using just the default menus? For me the most interesting reason is related to programming. A flag can be “set”(true) or “clear”(false). A flag is a “binary memory” which works as an indicator of calculator's status.
