Research on quadruple precision operation usable for scientific computation

通过本研究开发、评估和优化的四倍精度数值程序的应用，我们计算了小数点后第9位的布伦常数。新发现的数字是不知道的，直到完成布伦的数字。编写并提交了关于这一专题的论文供出版。这里，布伦常数是通过（1/p+1/（p+2））的和计算的常数，其中p（>=2）和p+2是素数。

Application of quadruple precision numerical routines which was developed, evaluated and optimized through this research, we had computed Brun's constant up to 9-th digit following decimal point. Newly found number is not know until the completion of the Brun's number. Papers on this topic were prepared and submitted for the publication. Here, Brun's constant is the constant computed by the sum of(1/p+1/(p+2)) where p(>=2) and p+2 is prime numbers.
