Why does sin 10 have a negative value in IC coding?

[LittleShade]

There is a problem converting the horizontal angle to the vertical angle because the value of the sine function is strange.

why? Does the sine function 10 have negative values?

[HydrO]

its in radians

sin 10 = -0.54402111088

you can convert degress to radians by multipliying by 0,0174533 (π / 180)

sin(10* (π / 180)) =0.17364817766

Formula is correct, wording is backwards. That formula converts Radians TO Degrees.

If he was expecting to obtain positive values then he was working with degrees, he would need to convert from degrees to radians so the wording is correct, but you are right the formula was the other way around, its fixed now, thanks

Thank you for everyone's help.
I forgot because it was old.

Thank you HydrO, JeanDeaux, Jan Mars
The result came out with your help.

Note in the latest update, we added constants for rad2deg and deg2rad to help with conversiuon instruction creation.

That's good news.
Thank you.
I don't think I can apply it right away because the server I play games on hasn't been updated yet.
