Functions
EXTERNRT OSREAL	rtxGetMinusInfinity (OSVOIDARG)
	Returns the IEEE negative infinity value.
EXTERNRT OSREAL	rtxGetMinusZero (OSVOIDARG)
	Returns the IEEE minus zero value.
EXTERNRT OSREAL	rtxGetNaN (OSVOIDARG)
	Returns the IEEE Not-A-Number (NaN) value.
EXTERNRT OSREAL	rtxGetPlusInfinity (OSVOIDARG)
	Returns the IEEE posative infinity value.
EXTERNRT OSBOOL	rtxIsMinusInfinity (OSREAL value)
	A utility function that compares the given input value to the IEEE 754 value for negative infinity.
EXTERNRT OSBOOL	rtxIsMinusZero (OSREAL value)
	A utility function that compares the given input value to the IEEE 754 value for minus zero.
EXTERNRT OSBOOL	rtxIsNaN (OSREAL value)
	A utility function that compares the given input value to the IEEE 754 value for Not-A-Number (NaN).
EXTERNRT OSBOOL	rtxIsPlusInfinity (OSREAL value)
	A utility function that compares the given input value to the IEEE 754 value for positive infinity.
EXTERNRT OSBOOL	rtxIsApproximate (OSREAL a, OSREAL b, OSREAL delta)
	A utility function that return TRUE when first number are approximate to second number with given precision.
EXTERNRT OSBOOL	rtxIsApproximateAbs (OSREAL a, OSREAL b, OSREAL delta)
	A utility function that return TRUE when first number are approximate to second number with given absolute precision.
