What are the commonly used methods in the Math class?

Commonly used methods in the Math class: 1. Basic mathematical operation method; 2. Trigonometric function method; 3. Logarithmic method; 4. Exponential method; 5. Random number method, etc.

In Java’s Math class, some commonly used mathematical methods are provided, including but not limited to the following:

1. Basic mathematical operation methods:

   • abs(x): Returns the absolute value of x.
   • ceil(x): Returns the smallest integer greater than or equal to x.
   • floor(x): Returns the largest integer less than or equal to x.
   • round(x): Returns the integer closest to x, rounded.
   • max(x, y): Returns the larger value of x and y.
   • min(x, y): Returns the smaller value of x and y.
   • pow(x, y): Returns x raised to the y power.
   • sqrt(x): Returns the square root of x.

2. Trigonometric function methods:

   • sin(x): Returns the sine value of x.
   • cos(x): Returns the cosine value of x.
   • tan(x): Returns the tangent value of x.
   • asin(x): Returns the arcsine value of x.
   • acos(x): Returns the arc cosine of x.
   • atan(x): Returns the arctangent value of x.

3. Logarithmic method:

   • log(x): Returns the natural logarithm of x (with e as the base).
   • log10(x): Returns the base 10 logarithm of x.

4. Exponent method:

   • exp(x): Returns e raised to the x power.

5. Random number method:

   • random(): Returns a random number between 0.0 and 1.0.

These are just some of the common methods in the Math class, and there are other methods that can be used for mathematical calculations. You can consult the official Java documentation or other related materials to learn more about the methods and usage of the Math class.
