p5.js |弧度()函数

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

句法：

radians( degrees )

参数：此函数接受要转换为弧度的单个参数度数。

返回值：返回角度转换后的弧度值。

下面的程序说明了 p5.js 中的 radians()函数：

示例 1：此示例使用 radians()函数将给定度数转换为其对应的弧度。

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);
} 

输出：

示例 2：此示例使用 radians()函数将给定度数转换为其对应的弧度。

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);
}  

输出：
