double MathSqrt(double x)

The MathSqrt function returns the square root of x. If x is negative, MathSqrt returns an indefinite (same as a quiet NaN).

MathSqrt 関数は x の平方根を返します。x が負の場合は、MathSqrt は不確定を返します（Quiet NaN と同じ）。

サンプル：

  double question=45.35, answer;
  answer=MathSqrt(question);
  if(question&lt;0)

  else
    Print("The square root of ",question," is ", answer);
  //Output: The square root of 45.35 is 6.73

double question=45.35, answer;

answer=MathSqrt(question);

if(question<0)

Print("Error: MathSqrt returns ",answer," answer");

else

Print("The square root of ",question," is ", answer);

//Output: The square root of 45.35 is 6.73
