Namespace: Numerics.NET
Assembly: Numerics.NET (in Numerics.NET.dll) Version: 9.0.7

Rationalize(Double)	Returns the rational number that exactly equals a floating-point real number.
Rationalize(Double, BigInteger)	Approximates a real number by a rational number whose numerator and denominator do not exceed the given value.

Returns the rational number that exactly equals a floating-point real number.

public static BigRational Rationalize(
	double x
)

Visual Basic

Public Shared Function Rationalize ( 
	x As Double
) As BigRational

C++/CLI

public:
static BigRational Rationalize(
	double x
)

static member Rationalize : 
        x : float -> BigRational

BigRational
The rational number that exactly equals x.

Approximates a real number by a rational number whose numerator and denominator do not exceed the given value.

public static BigRational Rationalize(
	double x,
	BigInteger maxValue
)

Visual Basic

Public Shared Function Rationalize ( 
	x As Double,
	maxValue As BigInteger
) As BigRational

C++/CLI

public:
static BigRational Rationalize(
	double x, 
	BigInteger maxValue
)

static member Rationalize : 
        x : float * 
        maxValue : BigInteger -> BigRational

x Double: The number to approximate.
maxValue BigInteger: The maximum value of the numerator and the denominator of the result.

BigRational
The rational number with numerator and denominator less than maxValue that is closest to x.

ArgumentOutOfRangeException	maxValue is less than zero.
ArgumentException	An approximation that satisfies the condition could not be found.
