Standing on the shoulders of Giants : NtRand3.3 rises. Achieving the precision of Excel 2010.

Sep 26, 2012

By adopting the calculation algorithm of Boost, the pioneering C++ open source library, NtRand 3.3 has greatly improved the accuracy of its distribution functions. In addition to this enhancement, NtRand 3.3 introduces seven new functions.

The precision of each distribution function in NtRand 3.3 now closely matches its corresponding Excel 2007 and 2010 function*.

For probability density function and cumulative distribution function of normal distribution—the most important distribution for every field—NtRand 3.3 can produce accurate values within the vast range of , which was only previously.
