FloatingPointComparison Methods 
The FloatingPointComparison type exposes the following members.
Name  Description  

CubeRoot 
Computes the realvalued cube root if a given number. The cube root of a negative value is the
negative of the cube root of that value's magnitude.
 
DivideRoundTripIsGreaterOrEqual 
Divides a dividend by a divisor such that if the quotient is later multiplied by the
divisor the result is greater than or equal to the dividend.
 
DivideRoundTripIsLessOrEqual 
Divides a dividend by a divisor such that if the quotient is later multiplied by the
divisor the result is less than or equal to the dividend.
 
EqualsSignificantDigits(Double, Double, Int32) 
Compares two numbers up to the specified number of significant digits.
 
EqualsSignificantDigits(Double, Double, Int32, Int32) 
Compares two numbers up to the specified number of significant digits.
 
EqualsSignificantDigitsOrAbsoluteError 
Compares two numbers up to the specified number of significant digits or by their absolute error.
 
GetVariableExponent 
Returns the order N of the given variable of the form: var * 10^(N+1) is less than 0.0
