int equal	(	const coefficient	x1,
		const coefficient	x2
	)		[inline]

Tests whether x1 is equal to x2.

void fixzero

(

coefficient &

number

)

[inline]

Puts number equal to 0 if it is close enough to 0.

int greaterequal	(	const coefficient	x1,
		const coefficient	x2
	)		[inline]

Tests whether x1 is greater than or equal to x2.

int greaterthan	(	const coefficient	x1,
		const coefficient	x2
	)		[inline]

Tests whether x1 is strictly bigger than x2. Fudges it a little bit to help with numerics.

int lessequal	(	const coefficient	x1,
		const coefficient	x2
	)		[inline]

Tests whether x1 is less than or equal to x2.

int lessthan	(	const coefficient	x1,
		const coefficient	x2
	)		[inline]

Tests whether x1 is strictly smaller than x2. Fudges it a little bit to help with numerics.
