p5.js中的unchar()函數用於將單字符字符串轉換為其相應的整數表示形式。該函數與char()函數相反。
用法:
unchar(value)
參數:此函數接受單個參數值,該值將轉換為其相應的整數表示形式。該值將是任何單字符字符串或單字符數組。
返回值:它返回轉換後的單字符字符串的整數表示形式。
以下示例程序旨在說明p5.js中的unchar()函數:
範例1:本示例使用unchar()函數將單字符字符串轉換為其相應的整數表示形式。
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);
}
輸出:
範例2:本示例使用unchar()函數將單字符字符串轉換為其相應的整數表示形式。
function setup() {
// Creating Canvas size
createCanvas(600, 200);
}
function draw() {
// Set the background color
background(220);
// Calling to unchar() function.
let A = unchar("A");
let B = unchar("b");
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);
}
