SQRT(n)


  • is any positive number.


Description

  • This function gives the square root of a positive real number.
  • Squaring is the value that can be multiplied by itself to give the original number.
  • The square root of a number is the inverse operation of squaring that number.
  • The root of a number is an equal factor of the number.
  • Every non-negative real number a has only one non-negative square root, called the principal square root, which is denoted by , where is called the radical sign or radix.
  • Square roots of positive whole numbers that are not perfect squares are always irrational numbers.
  • Numbers not expressible as a ratio of two integers .
    This function will give the result as NaN when n is a negative number.
