floating point - Round a float up to the next integer in javascript

Question

I need to round floating point numbers up to the nearest integer, even if the number after the point is less than 0.5.

For example,

• 4.3 should be 5 (not 4)
• 4.8 should be 5

How can I do this in JavaScript?

Answer 1

Use the Math.ceil^[MDN] function

var n = 4.3;
alert(Math.ceil(n)); //alerts 5
