This article mainly introduces "what math classes Javascript has". In daily operation, I believe many people have doubts about what math classes Javascript has. Xiaobian consulted various materials and sorted out simple and easy operation methods. I hope to help you answer the doubts about "what math classes Javascript has"! Next, please follow the small series to learn together!

description

random() returns a random number between 0 and 1. [ 0 , 1 )

The logarithm of ceiling (x) is rounded up.

floor(x) logarithm rounded down.

Round(x) to the nearest whole number.

examples

Math.PI pi console.log (Math.PI); // 3.141592653589793 Math. ceiling (num) rounded up to num console.log(Math. ceiling (4.2)); // 5 Math.floor(num) Rounds num downward console.log(Math.floor(4.2)); // 4 Math.round(num) rounds num to console.log (Math.round(1.8)); // 2 Math.abs(num) console.log(Math.abs(-0.78)); //0.78 Take the absolute value of num Math.pow(value1, value2) returns the value of 1 to the power 2 console.log (Math.pow(2,2)); // 4 returns the value of 1 to the power 2, here returns 2 to the power 2 Math.max(value1, value2, value3...) console.log (Math.max(5,8,47,54)); // 54, Returns the maximum value inside; Math.min(Value 1, Value 2, Value 3...) console.log (Math.min(5,8,47,54)); // 5 return the minimum value inside; Math.random(); Randomly returns decimals between 0 and 1, value range 0.0~1.0 (less than 1.0), random(no value is written inside) console.log(Math.random()*10+1); // Randomly returns decimals between 0 and 1, value range 0.0~1.0 (less than 1.0), random(no value is written inside) Here, if after *10+1, the value range is 1.0~11.0 (but less than 11), the study of "What math classes do Javascript have" is over, hoping to solve everyone's doubts. Theory and practice can better match to help everyone learn, go and try it! If you want to continue learning more relevant knowledge, please continue to pay attention to the website, Xiaobian will continue to strive to bring more practical articles for everyone!
