Priority: medium
Bug ID: 83288
Assignee: [email protected]
Summary: : sin and cos not calculated correctly
Severity: major
Classification: Unclassified
OS: Linux (All)
Reporter: [email protected]
Hardware: x86-64 (AMD64)
Status: UNCONFIRMED
Version: 4.2.4.2 release
Component: Spreadsheet
Product: LibreOffice
math functions are inaccurate as shown below.
sin 68 is 0.927183855. Calc returns a value of -0.897927681
cos 68 is 0.374606593. Calc returns a value of 0.440143022
tan 68 is 2.475086853. Calc returns a value of -2.040081598
The sin and cos errors have a serious affect on a business application that I
use so I have marked them "major".
I have not checked any other functions. The calculator in Ubuntu agrees with my
scientific calculator but Libre Office does not.
