Function Documentation

bool fp_equal	(	double	a,
		double	b
	)

Returns if a is equal to b, given some tolerance due to floating point arithmetic.

Parameters

a	The left-hand operator of "=="
b	The right-hand operator of "=="

Returns

If the first number is equal to the second.

bool fp_greater	(	double	a,
		double	b
	)

Returns if a is greater than b, given some tolerance due to floating point arithmetic.

Parameters

a	The left-hand operator of ">"
b	The right-hand operator of ">"

Returns

If the first number is greater than the second.

bool fp_less	(	double	a,
		double	b
	)

Returns if a is less than b, given some tolerance due to floating point arithmetic.

Parameters

a	The left-hand operator of "<"
b	The right-hand operator of "<"

Returns

If the first number is less than the second.

double fp_max	(	double	a,
		double	b
	)

Returns the maximum of a and b, given some tolerance due to floating point arithmetic.

Parameters

a	The first value to take the maximum over.
b	The second value to take the maximum over.

Returns

The maximum of the two numbers

double fp_min	(	double	a,
		double	b
	)

Returns the minimum of a and b, given some tolerance due to floating point arithmetic.

Parameters

a	The first value to take the minimum over.
b	The second value to take the minimum over.

Returns

The minimum of the two numbers
