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.
