Steps to Reproduce

1. Open a blank document in Keikai
2. Right click on cell A1
3. Select formatCell > Custom > "#,##0_);[Red](#,##0)"
4. Click OK
5. In cell A1, enter value 1.1, then press Enter
6. In cell A1, enter value 1.2, then press Enter

Current Result

Cell is correctly formatted as "1" after first edit
Cell is incorrectly formatted as "1.2" after 2nd edit

Expected Result

Cell is formatted as "1" in both cases

Debug Information

zss.Cell.prototype.setText checks for cell this.text value and compare with new value before setting.
this.text is the same formatted text (1.1 formats to 1, 1.2 formats to 1), so setText returns without updating the cell, since the value of this.text is already "1", even though the actual cell text from getText() is 1.2

Workaround

	<script><![CDATA[
		zk.afterLoad("zss", function () {
		    var _xCell = {};
		    zk.override(zss.Cell.prototype, _xCell, {
		    	setText: function (newText) {
		            if (!newText)
		                newText = "";
		            if (newText == this.text && newText == this.getText()) { // KEIKAI-168
		                return;
		            }
		            this._setText(newText);
		    	}
		     });
		});
