In this blog, we will learn the basic and most useful Math functions, available in JavaScript. These functions can be used for basic Math calculation.
  1. <script>
  2. //Math.abs()
  3. alert(Math.abs(-100.24)); //Returns Absolute value (value without negative
  4. or positive sign) of numbers.
  5. Output will be 100.24
  7. //Math.ceil()
  8. alert(Math.ceil(100.24)); //Rounds a number upwards to the nearest integer.
  9. Output will be 101
  11. //Math.floor()
  12. alert(Math.floor(100.85)); //Rounds a number downwards to the nearest integer.
  13. Output will be 100
  15. //Math.max()
  16. alert(Math.max(80, 100, 15, 75)); //Return the number with the highest value
  17. from the set of numbers.Output will be 100
  19. //Math.min()
  20. alert(Math.min(80, 100, 15, 75)); //Return the number with the lowest value
  21. from the set of numbers.Output will be 15
  23. //Math.pow()
  24. alert(Math.pow(5, 3)); //Returns value of first number to the power
  25. of second number(5 to the power of 3).
  26. Output will be 125
  28. //Math.random()
  29. alert(Math.random()); //Returns a random number between 0 and 1.
  31. //Math.round()
  32. alert(Math.round(100.50)); //Rounds a number to nearest integer.
  33. Output will be 101
  35. //Math.sqrt()
  36. alert(Math.sqrt(25)); //Returns Square root of a number.
  37. Output will be 5
  38. </script>
Hope, this will be helpful for someone out there.
