Functions

EXTERNRT OSREAL rtxGetMinusInfinity (void)
 Returns the IEEE negative infinity value.
EXTERNRT OSREAL rtxGetMinusZero (void)
 Returns the IEEE minus zero value.
EXTERNRT OSREAL rtxGetNaN (void)
 Returns the IEEE Not-A-Number (NaN) value.
EXTERNRT OSREAL rtxGetPlusInfinity (void)
 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.
