p5.js |度（）函数

p5.js 中的 degree ()函数用于将给定的弧度测量值转换为其对应的度值。

句法：

degrees( radian )

参数：此函数接受要转换为度数的单个参数弧度。

返回值：它将转换后的角度返回为度数。

下面的程序说明了 p5.js 中的 degree()函数：

示例 1：此示例使用 degree()函数将给定的弧度测量值转换为其对应的度值。

function setup() { 
   
    // Creating Canvas size
    createCanvas(450, 140); 
} 
  
function draw() { 
       
    // Set the background color 
    background(220); 
     
    // Initializing some angles in radians
    let Rad1 = PI; 
    let Rad2 = PI / 2; 
    let Rad3 = PI / 4; 
    let Rad4 = 67; 
      
      
    // Calling to degrees() function
    let A = degrees(Rad1);
    let B = degrees(Rad2);
    let C = degrees(Rad3);
    let D = degrees(Rad4);
      
    // Set the size of text 
    textSize(16); 
       
    // Set the text color 
    fill(color('red')); 
     
    // Getting converted angles into degree
    text("Converted angle in degree is: " + A, 50, 30);
    text("Converted angle in degree is: " + B, 50, 60);
    text("Converted angle in degree is: " + C, 50, 90);
    text("Converted angle in degree is: " + D, 50, 110);
} 

输出：

示例 2：此示例使用 degree()函数将给定的弧度测量值转换为其对应的度值。

function setup() { 
   
    // Creating Canvas size
    createCanvas(450, 140); 
} 
  
function draw() { 
       
    // Set the background color 
    background(220); 
      
    // Calling to degrees() function with different
    // radians value as parameter
    let A = degrees(PI/2);
    let B = degrees(PI/3);
    let C = degrees(PI/4);
    let D = degrees(PI/PI);
      
    // Set the size of text 
    textSize(16); 
       
    // Set the text color 
    fill(color('red')); 
     
    // Getting converted angles into degree
    text("Converted angle in degree is: " + A, 50, 30);
    text("Converted angle in degree is: " + B, 50, 60);
    text("Converted angle in degree is: " + C, 50, 90);
    text("Converted angle in degree is: " + D, 50, 110);
}  

输出：
