p5.js unchar() function

The unchar() function in p5.js is used to convert a single-character string into its corresponding integer representation. This function is just opposite to the char() function.

Syntax:

unchar(value)

Parameters: This function accepts single parameter value which is to be converted into its corresponding integer representation. This value will be any single-character string or an array of single-characters.

Return Value: It returns the converted integer representation of single-character string.

Below program illustrates the unchar() function in p5.js:

Example 1: This example uses unchar() function to converts a single-character string into its corresponding integer representation.

function setup() {

    // Creating Canvas size
    createCanvas(600, 230);
}

function draw() {

    // Set the background color
    background(220);

    // Initializing some values
    let Value1 = "A";
    let Value2 = "a";
    let Value3 = "B";
    let Value4 = "C";
    let Value5 = "z";

    // Calling to unchar() function.
    let A = unchar(Value1);
    let B = unchar(Value2);
    let C = unchar(Value3);
    let D = unchar(Value4);
    let E = unchar(Value5);

    // Set the size of text
    textSize(16);

    // Set the text color
    fill(color('red'));

    // Getting integer representation
    text("Integer representation of alphabet A is: " + A, 50, 30);
    text("Integer representation of alphabet a is: " + B, 50, 60);
    text("Integer representation of alphabet B is: " + C, 50, 90);
    text("Integer representation of alphabet C is: " + D, 50, 110);
    text("Integer representation of alphabet z is: " + E, 50, 140);
}

Output:

    let C = unchar("y");
    let D = unchar("Y");
    let E = unchar("P");

    // Set the size of text
    textSize(16);

    // Set the text color
    fill(color('red'));

    // Getting integer representation
    text("Integer representation of alphabet A is: " + A, 50, 30);
    text("Integer representation of alphabet b is: " + B, 50, 60);
    text("Integer representation of alphabet y is: " + C, 50, 90);
    text("Integer representation of alphabet Y is: " + D, 50, 110);
    text("Integer representation of alphabet P is: " + E, 50, 140);
}
