[. . . ] : Appears when statistics mode is selected. : Indicates that a numerical value is stored in the independent memory. : Indicates that the calculator is waiting for a numerical value to be entered, such as during simulation calculation. : Appears when the calculator shows an angle as the result in the complex calculation mode. x0 a y x2 b x x1 x3 variable, then press ® to confirm. The calculation result will be displayed after entering the value for all used variables. · Only numerical values are allowed as variables. · Upon completing the calculation, press to perform calculations using the same formula. · Variables and numerical values stored in the memories will be displayed in the variable input screen. To change a numerical value, input the new value and press ®. Error Codes and Error Types Syntax error (Error 1): · An attempt was made to perform an invalid operation. 2 +- 5 = Calculation error (Error 2): · The absolute value of an intermediate or final calculation result equals or exceeds 10100. · An attempt was made to divide by 0. [Last answer memory (ANS)] The calculation result obtained by pressing = or any other calculation ending instruction is automatically stored in the last answer memory. [Formula memories (F1 and F2)] : available only on EL-506V Formulas up to 80 characters each can be stored. As with storing numerical values in the memory, storing a new equation will automatically replace any existing equation in memory without notification. Note: Calculation results from the functions indicated below are automatically stored in memories X or Y. For this reason, when using these functions, be careful with the use of memories X and Y. · Random numbers . . . . . . . . . . . . . . . . . .
