Member Function Documentation

void Slope::make	(	const rat &	x0,
		const rat &	y0,
		const rat &	x1,
		const rat &	y1
	)

Initializes a slope.

Parameters:

x0,y0	Left endpoint defining the slope
x1,y1	Right endpoint defining the slope

Definition at line 41 of file geometry.cpp.

bool Slope::operator<

(

const Slope &

s

)

const

Defines an order on the slopes.

Parameters:

s	Slope to compare with

Returns:

True if and only is current slope less than s

Slope with type 'infty' never are less than any other slope. If rational, the slope is less than an 'infty' one and follows the order on rational numbers for the general case.
