PrecisionAlmostEqualNormRelativeT(T, T, Int32) Method

Compares two doubles and determines if they are equal to within the specified number of decimal places or not. If the numbers are very close to zero an absolute difference is compared, otherwise the relative difference is compared.

Namespace: Altaxo.Calc
Assembly: AltaxoCore (in AltaxoCore.dll) Version: 4.8.3179.0 (4.8.3179.0)
Syntax
C#
Copy
public static bool AlmostEqualNormRelative<T>(
	this T a,
	T b,
	int decimalPlaces
)
where T : Object, IPrecisionSupport<T>

Parameters

a  T
The first value.
b  T
The second value.
decimalPlaces  Int32
The number of decimal places.

Type Parameters

T

[Missing <typeparam name="T"/> documentation for "M:Altaxo.Calc.Precision.AlmostEqualNormRelative``1(``0,``0,System.Int32)"]

Return Value

Boolean

[Missing <returns> documentation for "M:Altaxo.Calc.Precision.AlmostEqualNormRelative``1(``0,``0,System.Int32)"]

Usage Note

In Visual Basic and C#, you can call this method as an instance method on any object of type T. When you use instance method syntax to call this method, omit the first parameter. For more information, see Extension Methods (Visual Basic) or Extension Methods (C# Programming Guide).
Remarks

The values are equal if the difference between the two numbers is smaller than 10^(-numberOfDecimalPlaces). We divide by two so that we have half the range on each side of the numbers, e.g. if decimalPlaces == 2, then 0.01 will equal between 0.005 and 0.015, but not 0.02 and not 0.00
