Description

Operators to convert from one type of measurement to another.

^< deg   Convert 'deg' into radians.
^> rad   Convert 'rad' into degrees.

Examples

Simple degree to radian (^<) examples:

r=^<d -- faster than r=math.rad(d)
radAngle=^<sprite:getRotation()
pi=^<180 -- pi is 3.142 in radians or 180 in degrees

Simple radian to degree (^>) examples:

d=^>r -- faster than d=math.deg(r)
sprite:setRotation(^>math.sin(0.5))
