owens_t_T6 misplaced parenthesis

[mwelinder@…]

In http://www.boost.org/doc/libs/1_53_0/boost/math/special_functions/owens_t.hpp in function owens_t_T6 you will see the line...

const RealType r = atan2(y, static_cast<RealType>(1 + a) );

which should have been

const RealType r = atan2(y, static_cast<RealType>(1) + a );

It probably doesn't matter much, though.

Ah no, the original code is correct:

We require mixed arithmetic between the floating point type and all builtin arithmetic types as part of our conceptual requirements, so 1 + a is always supported.

The cast is there in case the type of "a" uses expression templates (ie 1 + a returns a type other than the type of "a").
