Steps to Reproduce

Run keikai with library property

<library-property>
<name>io.keikai.spreadsheet.showZeroValues</name>
<value>false</value>
</library-property>

type value in sheet 1 (any cell): 0.3
switch to sheet 2
switch to sheet 1

Current Result

values that if converted to integer round to zero are hidden by the showZeroValues set to false

Expected Result

only cells with values strictly equal to zero should be hidden

Debug Information

Cause by ((Number) value).intValue() == 0 check
rounds the value before comparing to zero
