->HMS doesn't work properly

[AveDonat]

Hi everyone,

I have a problem with the ->HMS function. My angle is: 1.96834347921E-7 . In excel, when I used the function DEGREES(), the result was 1.1278E-5 . But when I used the ->HMS function on my HP 50g calculator to convert the angle from decimal form to HMS form, the result was 7.08603652516E-8.

Can you guys tell me what is the problem?

Thank you.
