Subject: [Boost-users] Box-Muller - normal distributed random numbers

Hi,
I wonder why _cached_rho is calclulated this way:
sqrt(-result_type(2) * log(result_type(1)-_r2));
in normal_distribution.hpp:70 and not
sqrt(-result_type(2) * log(_r2));
So I don't understand why there is "result_type(1) - _r2" instead of just
"_r2".
Cheers!
