template<class T >

IMATH_HOSTDEVICE IMATH_CONSTEXPR14 bool equalWithAbsError	(	T	x1,
		T	x2,
		T	e
	)

inline

Compare two numbers and test if they are "approximately equal":

Returns

Ttrue if x1 is the same as x2 with an absolute error of no more than e:

abs (x1 - x2) <= e

Definition at line 152 of file ImathMath.h.

template<class T >

IMATH_HOSTDEVICE IMATH_CONSTEXPR14 bool equalWithRelError	(	T	x1,
		T	x2,
		T	e
	)

inline

Compare two numbers and test if they are "approximately equal":

Returns: True if x1 is the same as x2 with an relative error of no more than e,

abs (x1 - x2) <= e * x1

Definition at line 165 of file ImathMath.h.

template<class T >

IMATH_INTERNAL_NAMESPACE_HEADER_ENTER IMATH_HOSTDEVICE T sinx_over_x ( T x )

inline

Don Hatch's version of sin(x)/x, which is accurate for very small x. Returns 1 for x == 0.

Definition at line 136 of file ImathMath.h.
