Public Function Approx( _ ByVal vX As Variant _ , ByVal vY As Variant _ , Optional ByVal vEpsilon As Double = 0.00000000000001 _ ) As Variant
Approx(34.6, 34.59999999) = False Approx(34.6, 34.599999999999) = True Approx("SA", "sa") = False Approx("SA", "SA") = TrueSee also:
ApproxVerify Subroutine ApproxComplex Function Debug.Assert (Visual Basic)vX: First of two numbers that are compared to see if they are approximately equal. Function returns Null if vX is Null or cannot be fixed up to a Double precision floating point number. (as defined by the ComplexStringToReals function).
vY: Second of two numbers that are compared to see if they are approximately equal. Function returns Null if vY is Null or cannot be fixed up to a Double precision floating point number.
Note: If either of the arguments are not numbers, this function compares the values using the EqualLikeDataType function; it passes the arguments to that function and returns its result. In this case, it uses EqualLikeDataType with the Compare Mode of vbBinaryCompare.
vEpsilon: Defines the range of "approximate" values as defined below. vEpsilon defaults to 1E-14 (10 ^ -14) if it is missing.
If Y == 0: Abs(X) < Epsilon If Y <> 0: Abs(Y - X) / Y) < Epsilonv1.5 Addition: This function is new to this version of Entisoft Tools. It is a version of the ApproxComplex function which supports only real numbers.
