Detailed Description

template<class SourceType, class DestContext>
class plll::arithmetic::implementation::conversion_impl< SourceType, DestContext >

Provides conversion implementation from type SourceType to DestContext::Type.

Every instantiation should provide the following member types:

  • RetVal: return value for the convert() function.
  • RetVal_Frac: return value for the convert_frac() function. Should be void if DestContext::is_real is false.
  • RetVal_Floor: return value for the convert_floor() function. Should be void if DestContext::is_int is false or type_traits<SourceType>::is_real is false
  • RetVal_Round: return value for the convert_round() function. Should be void if DestContext::is_int is false or type_traits<SourceType>::is_real is false
  • RetVal_Round2: return value for the convert_round() function which also retrieves rounding information. Should be void if DestContext::is_int is false or type_traits<SourceType>::is_real is false
  • RetVal_Ceil: return value for the convert_ceil() function. Should be void if DestContext::is_int is false or type_traits<SourceType>::is_real is false

The following static functions should always be provided:

  • void convert(typename Context::Type &, const typename Context::Type &, const Context &)
  • RetVal convert(const typename Context::Type &, const Context &)

The following static functions should be provided if DestContext::is_real is true:

  • void convert_frac(typename Context::Type &, const typename Context::Type &, const typename Context::Type &, const Context &)
  • RetVal_Frac convert_frac(const typename Context::Type &, const typename Context::Type &, const Context &)

The following static functions should be provided if both DestContext::is_int and type_traits<SourceType>::is_real are true:

  • void floor(typename Context::Type &, const typename Context::Type &, const Context &)
  • RetVal_Floor floor(const typename Context::Type &, const Context &)
  • void round(typename Context::Type &, const typename Context::Type &, const Context &)
  • RetVal_Round round(const typename Context::Type &, const Context &)
  • void round(typename Context::Type &, const typename Context::Type &, bool &, const Context &)
  • RetVal_Round2 round(const typename Context::Type &, bool &, const Context &)
  • void ceil(typename Context::Type &, const typename Context::Type &, const Context &)
  • RetVal_Ceil ceil(const typename Context::Type &, const Context &)
