p5.js exp() 方法
exp()函数将 n 的值(任意数)返回到欧拉数 e(2.71828…) 的 n 次幂 (e^n)。
句法:
exp(n)
参数:此方法接受单个参数n即数字值。
返回值:返回给定数字的 (e^n)。
示例 1:
Javascript
function setup() {
// Create Canvas of size 270*80
createCanvas(600, 300);
}
function draw() {
// Set the background color
background(220);
// Initialize the parameter and
// return the value of the function
let n = exp(1.1)
let m = exp(3.3)
// Set the size of text
textSize(16);
text( "Result in Eular number will be :" + n, 50, 50);
text( "Result in Eular number will be :" + m, 50, 80);
}
Javascript
function setup() {
// Create Canvas of size 270*80
createCanvas(600, 500);
}
function draw() {
let x, m;
let step = 50
// Set the background color
background(220);
// Initialize the parameter and return
// the value of the function
// For loop is set from numbert 0 to 10.
for( x = 0; x <= 10; x++) {
// The return value of exp() function
m = exp(x)
text( "Result for " + x +
": " + m, 50, step);
step = step + 30;
}
// Set the size of text
textSize(17);
// Set the text color
fill(color('blue'));
}
输出:
