rad2deg

rad2deg(x)

Convert x from radians to degrees

Examples

1. Convert radians to degrees:

   julia> rad2deg(pi/2)
   90.0

   This example converts π/2 radians to degrees, which is equal to 90 degrees.

2. Convert an array of angles to degrees:

   julia> angles = [pi/4, pi/3, pi/6];
   julia> rad2deg.(angles)
   3-element Array{Float64,1}:
   45.0
   60.0
   30.0

   It applies rad2deg element-wise to an array of angles, converting them from radians to degrees.

3. Convert a single value to degrees:

   julia> angle = 2pi;
   julia> rad2deg(angle)
   360.0

   It converts a single value, 2π, from radians to degrees.

Common mistake example:

julia> rad2deg("pi/4")
ERROR: MethodError: no method matching rad2deg(::String)

In this example, an incorrect input type is provided. The rad2deg function expects a numerical value representing an angle in radians. Ensure that the input value is of the correct type to avoid such errors.
