p5.js | char() function

The char() function in p5.js is used to convert the given string or number value into its corresponding single-character string representation. If the input parameter is a string value then at first it gets converted into its integer equivalent internally after that its single-character string is represented as output and when an array of strings or number is taken as the parameter then it gives output as an individual single-character strings for each element of the array.

Syntax:

char( value )

Parameters: This function accepts single parameter value which is to be converted into its single-character string representation. This value might be a number, string of numbers and an array of strings or numbers.



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

Below programs illustrate the char() function in p5.js:

Example 1: This example uses char() function to convert input value into its corresponding character.

    // Set the text color 
    fill(color('red')); 
     
    // Getting character representation
    text("Character representation of value 66 is: " + A, 50, 30);
    text("Character representation of value 67 is: " + B, 50, 60);
    text("Character representation of string '65' is: " + C, 50, 90);
    text("Character representation of value 62 is: " + D, 50, 110);
    text("Character representation of string '62' is: " + E, 50, 140);
    text("Character representation of value 90 is: " + F, 50, 170);
