degrees function

The degrees function converts the specified expression from radians to degrees.

Syntax:

double degrees(n)

Semantics:

n: The argument n is expressed in radians. Here, n is an expression that resolves to a number.
return type: double.
- Returns a NULL value in the following cases:
  - n resolves to a NULL value
  - n does not resolve to a number
- Returns NaN if n resolves to NaN.
- Returns respective infinity if n resolves to positive/negative infinity.

Note:

The conversion from radians to degrees does not generally return an exact value. For example, consider the query:

SELECT degrees(atan(sqrt(3))) AS ATAN60 FROM Archery

The degrees to radians conversion results in: {"ATAN60":59.99999999999999}

Example:

SELECT degrees(n) FROM Archery

Value of n	Output
pi()/2	90
0	0.0
