p5.js中的hex()函数用于将数字转换为十六进制表示法。
用法:
hex(Number)
参数:该函数接受参数Number,该参数将转换为十六进制形式。此参数也可以是数字数组。
返回值:它返回转换后的十六进制表示形式。
以下示例程序旨在说明p5.js中的hex()函数。
示例1:
function setup() {
// Creating Canvas size
createCanvas(600, 200);
}
function draw() {
// Set the background color
background(220);
// Initializing some numbers
let Number1 = 20;
let Number2 = 255;
let Number3 = 0;
let Number4 = 25;
let Number5 = 70;
// Calling to hex() function.
let A = hex(Number1);
let B = hex(Number2);
let C = hex(Number3);
let D = hex(Number4);
let E = hex(Number5);
// Set the size of text
textSize(16);
// Set the text color
fill(color('red'));
// Getting hexadecimal notation
text("Hexadecimal representation of 20 is: " + A, 50, 30);
text("Hexadecimal representation of 255 is: " + B, 50, 60);
text("Hexadecimal representation of 0 is: " + C, 50, 90);
text("Hexadecimal representation of 25 is: " + D, 50, 110);
text("Hexadecimal representation of 70 is: " + E, 50, 140);
}
输出:
示例2:
function setup() {
// Creating Canvas size
createCanvas(650, 100);
}
function draw() {
// Set the background color
background(220);
// Initializing some numbers
let Number1 = [20, 255, 30];
let Number2 = [255, 7, 9];
// Calling to hex() function.
let A = hex(Number1);
let B = hex(Number2);
// Set the size of text
textSize(16);
// Set the text color
fill(color('red'));
// Getting hexadecimal notation
text("Hexadecimal representation of [20, 255, 30] is: "
+ A, 50, 30);
text("Hexadecimal representation of [255, 7, 9] is: "
+ B, 50, 60);
}
