◆ ldtox80

#define ldtox80	(	x,
		x80
	)

Value:

  do                         \
  {                          \
    double d = (double)*(x); \
    dtox80(&d, (x80));       \

		extended80 *	x80
	)

◆ ldtox80()

void ldtox80	(	const long double *	x,
		extended80 *	x80
	)

◆ x80tod()

double x80tod ( const extended80 * x80 )

MathLib v2 has two new transfer functions: x80tod and dtox80. They can be used to directly transform 68k 80-bit extended data types to double and back for PowerPC based machines without using the functions x80told or ldtox80. Double rounding may occur. x80tod()

void x80told	(	const extended80 *	x80,
		long double *	x
	)
