The next table provides an overview of intrinsic functions to convert fractional values. Note that the TASKING VX-toolset C compiler for TriCore fully supports the fractional type so normally you should not need these intrinsic functions (except for __mulfractlong). For compatibility reasons the TASKING C compiler does support these functions.
