Conversion

The AST (Abstract Syntax Tree) Builder in GlueSQL provides mathematical conversion functions like degrees and radians. These functions convert angles expressed in radians to degrees and vice versa.

For the sake of this tutorial, we'll assume there's a table named Number with columns input (of type INTEGER) and number (of type FLOAT).

Degrees Function

The degrees function converts an angle from radians to degrees.

You can call this function in two ways in GlueSQL:

let actual = table("Number")
    .select()
    .project("input")
    .project(degrees("number"))  // Method 1: Using the degrees function directly
    .project(col("number").degrees())  // Method 2: Calling the degrees method on a column
    .execute(glue)
    .await;

Radians Function

The radians function converts an angle from degrees to radians.

Just like with the degrees function, there are two ways to call this function:

let actual = table("Number")
    .select()
    .project("input")
    .project(radians("number"))  // Method 1: Using the radians function directly
    .project(col("number").radians())  // Method 2: Calling the radians method on a column
    .execute(glue)
    .await;
