User manual SHARP EL-520E

[. . . ] Speed of light in vacuum After reading this manual, store it in a convenient location for future reference. Do not carry the calculator around in your back pocket, as it may break when you sit down. Keep the calculator away from extreme heat such as on a car dashboard or near a heater, and avoid exposing it to excessively humid or dusty environments. Since this product is not waterproof, do not use it or store it where fluids, for example water, can splash onto it. [. . . ] [Random Coin] To simulate a coin flip , 0 (head) or 1 (tail) can be randomly generated by pressing @`2®. [Random Integer] An integer between 0 and 99 can be generated randomly by pressing @`3®. Each time @g are pressed, the angular unit changes in sequence. Press R and a variable key to recall a value from the memory. to place a variable in an equation , press K and a variable key. [Independent memory (M)] In addition to all the features of temporary memories, a value can be added to or subtracted from an existing memory value. Press ªOM to clear the independent memory (M). [Last answer memory (ANS)] The calculation result obtained by pressing = or any other calculation ending instruction is automatically stored in the last answer memory. note: · Calculation results from the functions indicated below are automatically stored in memories X or Y replacing existing values. X memory (r or x), Y memory ( or y) · Use of R or K will recall the value stored in memory using up to 14 digits. The previous calculation result can be used in the subsequent calculation. However, it cannot be recalled after entering multiple instructions. Arithmetic operations and memory calculations can be performed using fractions, and conversion between a decimal number and a fraction. If the number of digits to be displayed is greater than 10, the number is converted to and displayed as a decimal number. Conversions can be performed between N-base numbers. The four basic arithmetic operations, calculations with parentheses and memory calculations can also be performed, along with the logical operations AND, OR, NOT, NEG, XOR and XNOR on binary, pental, octal and hexadecimal numbers. Conversion to each system is performed by the following keys: @ ê (" " appears. ) Note: The hexadecimal numbers A ­ F are entered by pressing ß, TM, L, ÷ When a decimal number having a fractional part is converted into a binary, pental, octal, or hexadecimal number, the fractional part will be truncated. Conversion between decimal and sexagesimal numbers can be performed, and, while using sexagesimal numbers, conversion to seconds and minutes notation. The four basic arithmetic operations and memory calculations can be performed using the sexagesimal system. A constant is recalled by pressing ß followed by the number of the physical constant designated by a 2-digit number. The recalled constant appears in the display mode selected with the designated number of decimal places. [. . . ] Within the ranges specified, this calculator is accurate to ±1 of the least significant digit of the mantissa. However, a calculation error increases in continuous calculations due to accumulation of each calculation error. , where continuous calculations are performed internally. Be sure to observe the following handling rules: · Do not mix new and old batteries. [. . . ]
