p5.js中的radians()函數用於將給定的度數測量值轉換為相應的弧度值。
用法:
radians( degrees )
參數:該函數接受單個參數度,該度將轉換為弧度。
返回值:它返回角度的轉換弧度值。
以下程序說明了p5.js中的radians()函數:
示例1:本示例使用radians()函數將給定度數轉換為其對應的弧度。
function setup() {
// Creating Canvas size
createCanvas(450, 140);
}
function draw() {
// Set the background color
background(220);
// Initializing some angles in degree
let Deg1 = 0;
let Deg2 = 30;
let Deg3 = 60;
let Deg4 = 90;
// Calling to radians() function.
let A = radians(Deg1);
let B = radians(Deg2);
let C = radians(Deg3);
let D = radians(Deg4);
// Set the size of text
textSize(16);
// Set the text color
fill(color('red'));
// Getting converted angles into radians
text("Converted angle in radian is: " + A, 50, 30);
text("Converted angle in radian is: " + B, 50, 60);
text("Converted angle in radian is: " + C, 50, 90);
text("Converted angle in radian is: " + D, 50, 110);
}
輸出:
示例2:本示例使用radians()函數將給定度數轉換為其對應的弧度。
function setup() {
// Creating Canvas size
createCanvas(450, 140);
}
function draw() {
// Set the background color
background(220);
// Calling to radians() function with different
// degrees value as parameter
let A = radians(90);
let B = radians(180);
let C = radians(60);
let D = radians(45);
// Set the size of text
textSize(16);
// Set the text color
fill(color('red'));
// Getting converted angles in radians
text("Converted angle in radian is: " + A, 50, 30);
text("Converted angle in radian is: " + B, 50, 60);
text("Converted angle in radian is: " + C, 50, 90);
text("Converted angle in radian is: " + D, 50, 110);
}
輸出:
