What are the math methods in JavaScript?

The methods of the Math object are: abs(), acos(), asin(), atan(), cos(), floor(), log(), max(), min(), pow( ), random(), round(), sin(), sqrt(), tan(), exp(), etc.

The operating environment of this tutorial: Windows 7 system, ECMAScript version 5, Dell G3 computer.

Math objects are used to perform mathematical tasks.

Methods of Math object

• abs(x): Returns the absolute value of the number.

• acos(x): Returns the arc cosine of the number.

• #asin(x): Returns the arcsine value of the number.

• atan(x): Returns the arctangent of x as a value between -PI/2 and PI/2 radians.

• atan2(y,x): Returns the angle from the x-axis to the point (x,y) (between -PI/2 and PI/2 radians).

• #ceil(x): Round up the logarithm.

• cos(x): Returns the cosine of the number.

• #exp(x): Returns the exponent of e.

• #floor(x): Round down the logarithm.

• #log(x): Returns the natural logarithm of the number (base is e).

• max(x,y): Returns the highest value between x and y.

• min(x,y): Returns the lowest value between x and y.

• pow(x,y): Returns x raised to the y power.

• random(): Returns a random number between 0 ~ 1.

• #round(x): Round the number to the nearest integer.

• #sin(x): Returns the sine of the number.

• sqrt(x): Returns the square root of the number.

• tan(x): Returns the tangent of the angle.

• #toSource(): Returns the source code of the object.

• #valueOf(): Returns the original value of the Math object.
