angle conversion

[DSparrow]

I have been using the code, but the data i get in return is in negative numbers. Specifically, we are looking at the pitch, data[4] from the array i think, but it returns the following from a resting position with the person wearing the HMD loking up :
-4.51560783386 (resting point)
-4.51560783386
-4.51560783386
-5.21056461334
-6.53081417084
-6.53005409241
-6.64580345154
-7.05755376816
-9.14772891998
-11.3136796951
-12.8152256012
-14.2895698547
-15.4270544052
-17.0076580048
-18.5268325806
-18.4219417572
-16.7005977631
-10.3614425659

should I just ignore the negative sign?
Thanks again for the help.
