degrees

Use the degrees function in APL to convert an angle from radians to degrees. The conversion formula is degrees = (180 / π) × angle_in_radians.

degrees is useful whenever you compute angles using trigonometric or inverse trigonometric functions, which return values in radians, but need the result expressed in degrees for display or comparison. For example, you can convert the output of atan2 or acos into a degree value that's easier to interpret.

Usage

Syntax

degrees(a)

Parameters

Returns

The angle in degrees corresponding to the input radian value.

Example

Use degrees to convert an angle in radians to degrees.

Query

print result = degrees(pi())

Output

List of related functions

• radians: Converts degrees to radians. Use it for the inverse conversion before passing values to trigonometric functions.
• pi: Returns the constant π. Use it in manual radian-to-degree conversions as an alternative to degrees.
• cos: Returns the cosine of an angle in radians. Use degrees to convert its output for display.
• sin: Returns the sine of an angle in radians. Use degrees to convert angular results.
• atan2: Returns an angle in radians from two coordinates. Use degrees to convert its output to degrees.
