[Boost-users] [math] log_max_value<long double>

19 Mar 2009

      Hi All,

Was this discussed before?

<cmath>

using namespace math::tools;

typedef double RealType;
log_max_value<RealType>()     709
log(max_value<RealType>())    709.783
!math::isinf(exp(log_max_value<RealType>())) //true

typedef long double RealType;
log_max_value<RealType>()     11356
log(max_value<RealType>())    inf
!math::isinf(exp(log_max_value<RealType>())) //false

i.e. exp in cmath seems to "assume" RealType = double.
