Casio fx-100W, fx-115W, fx-570W, fx-991W kCoordinate Conversion (Pol(x, y), Rec (r, θ)), F FFFF, AF 2 P60 T, Af1 P L3 T, E-18, 9 \ 10, •Example: 910 = 0.9 m (milli)

*For displayed values, the calculator selects the ENG sym- bol that makes the numeric part of the value fall within the range of 1 to 1000.

*ENG symbols cannot be used when inputting fractions.*The ENG mode cannot be used in combination with the CMPLX, or BASE-N modes.

•Performing any of the key operations in the above table while you are not in the ENG mode inputs the exponen- tial value in the “Unit” column (without inputting the ENG symbol).

•Example: 910 = 0.9 m (milli)

F FFFF 1	0.
	ENG

9 \ 10 =	9 1	m
		900.

In the ENG mode, even standard (non-ENG) calculation results are displayed using ENG symbols.

AP 0.9

9 1 m

J 900.

kCoordinate Conversion (Pol(x, y), Rec (r, θ))

•Calculation results are automatically assigned to vari- ables E and F.

•Example 1: To convert polar coordinates (r2, 60°) to rectangular coordinates (x, y) (DEG mode)

x	AF 2 P60 T=	1.
		R

y0o 1.732050808

•0 n, 0 o swaps displayed value with value in memory.

•Example 2: To convert rectangular coordinates (1,3) to polar coordinates (r, ) (RAD mode)

r	Af1 P L3 T=	2.
