Method of implementing an electronic calculator function in a portable terminal
First Claim
1. A method of implementing an electronic calculator function in a portable terminal having a display, comprising the steps of:
- setting an electronic calculator mode;
displaying separately on the display;
a first input window which receives and displays therein numeric information subject to arithmetic operation, a second input window which receives and displays therein operation/control commands, and an output window which displays therein an information input state and a result of the operation;
displaying the numeric information in the output window when the corresponding information is inputted through the first input window;
performing an operation on the numeric information displayed in the output window when the operation/control commands are inputted through the second input window;
reducing a size of the first and second input windows to allow the output window to increase in size when needed to display additional resultant numeric information; and
displaying resultant numeric information, resulting from the operation, in the output window.

Abstract
A method of implementing an electronic calculator function in a portable terminal having a display comprises the steps of: setting an electronic calculator mode; displaying separately on the display: a first input window which receives and displays therein numeric information subject to arithmetic operation, a second input window which receives and displays therein operation/control commands, and an output window which displays therein an information input state and a result of the operation; displaying the numeric information in the output window when the corresponding information is inputted through the first input window; performing an operation on the numeric information displayed in the output window when the operation/control commands are inputted through the second input window; and displaying resultant numeric information, resulting from the operation, in the output window. The size of the output window may be increase as needed by reducing the sizes of the first and second input windows.

6. A method of implementing an electronic calculator function in a portable terminal with a display, comprising:
-
displaying a first input window which has divided regions corresponding to numeric information and receiving input numeric information;
displaying a second input window which has divided regions corresponding to operation/control commands and receiving input operation/control commands;
displaying an output window for displaying the input numeric information and for subsequently displaying resultant numeric information, resulting from performing an arithmetic operation on the input numeric information according to the received input operation/control commands displayed in the second input window; and
reducing a size of the first and second input windows to allow the output window to increase in size when needed to display additional resultant numeric information. - View Dependent Claims (7, 8, 9, 10, 11, 12)
