Command 5 - Data Range Setup
*1 Polynomial: Input constants in sequence, from n = 0 to 9. *2 Mixed polynomial: Input constants in sequence from m = 4 to 1, and n = 0 to 5.
*3 Input of zero for constants can be skipped if all remaining constants are not used. *4 Input 0 for constants that are not used.
• When the conversion result of the “conversion equation” selected by Command 4 causes an overflow, the EA-200 sends a result of zero (0) to the calculator.
