typedef vnl_rational vnl_numeric_traits< vnl_rational >::abs_t

Return value of abs().

Definition at line 23 of file vnl_rational_traits.h.

typedef vnl_rational vnl_numeric_traits< vnl_rational >::double_t

Name of a type twice as long as this one for accumulators and products.

Definition at line 25 of file vnl_rational_traits.h.

typedef double vnl_numeric_traits< vnl_rational >::real_t

Name of type which results from multiplying this type with a double.

Note that this requires an explicit cast from double to vnl_rational. This must be a built-in type: do not set this to vnl_rational, since that would require std::sqrt(vnl_rational) etc., which is not allowed.
