A Number of Input Characters (Bytes) As you input a mathematical expression, it is stored in memory called an “input area,” which has a capacity of 127 bytes. This means you can input up to 127 bytes for a single mathematical expression. When linear display is selected as the display format, each function normally uses one or two bytes of memory. With the natural display format, each function use four or more bytes of memory. For more information, see “Inputting Calculation Expressions Using
