sin/cos functions take parameter as Angle not Radian

[jesseky]

This way looks a little weird, sin(pi/2) should return 1.0 instead of 0.0274121335, maybe you can consider supporting both radian and angle, such as sin(90deg) or sin(90°) return 1.0, and sin(pi/2) or sin(1.5707963268) return 1.0

a little suggestion.

Great work, thank you!

Hiya,

eva has deg and rad functions for conversions between degree and radians, so you would have to do sin(deg(pi/2)) to get 1.0.

If you don't like this however, you can start eva in radian mode, with eva -r, that switches all trigonometric functions to take input in radian, sin(pi/2) would return 1.0 then :)
