Functions
double	moab::anonymous_namespace{IntegerReprosum.cpp}::frac_and_exp (double x, int &exp_out)
	Fortran-equivalent fraction(x) for radix-2 doubles: returns f in [0.5, 1) (or in (-1, -0.5] for negative x) and stores the exponent so that x = f * 2^e Same as std::frexp. More...
double	moab::anonymous_namespace{IntegerReprosum.cpp}::scale2 (double x, int n)
	Fortran-equivalent scale(x, n) for radix-2 doubles: returns x * 2^n. Same as std::ldexp. More...
double	moab::anonymous_namespace{IntegerReprosum.cpp}::set_exp (double x, int e)
	Fortran-equivalent set_exponent(x, e): returns a value with the same fraction as x but with exponent e. Same as ldexp(frexp(x, &dummy), e) More...
int64_t	moab::anonymous_namespace{IntegerReprosum.cpp}::i2pow (int k)
	MPI_INT64_T equivalent for our int64 type. Use MPI_LONG_LONG_INT for portability across MPI implementations that don't yet expose MPI_INT64_T as a primary datatype. More...
