DEGREES in JS

Description

JavaScript does not provide a method to convert radians to degrees of a given angle. This could be calculated using the equation: $Degrees = \frac{180^{\circ}}{\pi} \cdot angle$

Sample Source Pattern

Implementation example

function degress(angle){
    return (180/Math.PI) * angle;
}

Arguments

angle: Numeric expression in radians.

Return Type

Same data type sent through parameter as a numeric expression.

Examples

Query

CREATE OR REPLACE FUNCTION compute_degrees(angle float)
  RETURNS float
  LANGUAGE JAVASCRIPT
AS
$$
  function degrees(angle){
    return (180/Math.PI) * angle;
  }
  return degrees(ANGLE);
    
$$
;
SELECT COMPUTE_DEGREES(PI());

Result

COMPUTE_DEGREES(PI())|
---------------------+
                180.0|
