What are the math methods in JavaScript?

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.
