Function Documentation

nextafter()

double nextafter	(	double	x,
		double	y
	)

Next representable value.

The nextafter functions determine the next representable value, in the type of the function, after x in the direction of y, where x and y are first converted to the type of the function. The nextafter functions return y if x equals y. A range error may occur if the magnitude of x is the largest finite value representable in the type and the result is infinite or not representable in the type.

Parameters

x	Base value.
y	Value toward which the return value is approximated.

Returns

The nextafter functions return the next representable value in the specified format after x in the direction of y.
