The following editor will bring you a detailed discussion of the properties and methods of the built-in object Math in js. Let me share it with you now and give it as a reference for everyone.

Attributes:

constructor function reference of the created object

prototype attributes and methods that can be added to the object

E Euler’s constant, the base of the natural logarithm (approximately equal to 2.718)

LN2 The natural logarithm of 2 (approximately equal to 0.693)

LN10 The natural logarithm of 10 (approximately Equal to 2.302)

LOG2E The logarithm of e with base 2. (approximately equal to 1.442)

LOG10E The logarithm of e with base 10 (approximately equal to 0.434)

The value of PI ∏ (approximately equal to 3.14159)

SQRT1_2 The square root of 1/2 (0.5) (that is, l divided by the square root of 2, approximately equal to o.707)

SQRT2 2 Square root (approximately equal to 1.414)

Method:

abs(x) Returns the absolute value of the number

acos(x ) Returns the arc cosine of a number

asin(x) Returns the arc sine of a number

atan(x) Returns the arc tangent between -PI/2 and PI/2

atan2(y,x) Returns the angle of (x,y) between -PI and PI

ceil(x) Returns the largest integer of x after rounding

cos(x ) Returns the cosine of a number

exp(x) Returns the E^x value

floor(x) Returns the smallest integer of x after rounding

log(x) Returns The base is the natural logarithm of E

max(x,y) Returns the larger number between x and y

min(x,y) Returns the smaller number between x and y Number

pow(x,y) Returns the value of y^x

random() Returns a random function between 0 and 1

round(x) after rounding Rounding

sin(x) Returns the sine of a number

sqrt(x) Returns the square root of a number

tan(x) Returns the tangent of an angle

toSource() Display the source code of the object

valueOf() Return the original value of the mathematical object

The above is what I compiled for everyone. I hope it will be helpful to everyone in the future.
