To round a number in the display screen to a specified number of decimal places, set the display format to show the exact number of decimal places desired. Each time a calculator function is performed, the value displayed will be rounded automatically. However, the value before rounding is actually stored in the register. To permanently round a value, touch b RND. To see the full value of a number (without rounding) touch b PREFIX.

Example

ENTRIES				DISPLAY
				99.13
99.1266			ENTER
				Displays the rounded value.
				99.126600000
b	PREFIX
				Displays the entire value for a short pause.
				99.13
b		RND
				Displays the original value.
				99.130000000
b	PREFIX			Displays the entire value for a short pause after
				permanent rounding.

Factorial Values

When r n! is touched, the factorial of the value on the display screen is calculated. (the product of the values of integers 1 to n, being the number on the display screen)

Example

ENTRIES DISPLAY

720.00

6 r n! Displays the factorial value of 6 (1 X 2 X 3 X 4 X 5 X 6).

Exponential Values

When r ex is touched, the exponential of the value on the display screen is calculated (raises the base number –e- to the number on the display screen)>
