RADIANS in JS

Description

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

Sample Source Pattern

Implementation example

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

Arguments

angle: Float expression in degrees.

Return Type

Same data type sent through parameter as a numeric expression in radians.

Examples

Query

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

Result

RADIANS(180)     |
