PrecisionIsSmaller(Double, Double, Int32) Method

Compares two doubles and determines if the first value is smaller than the second value to within the specified number of decimal places or not.

Namespace: Altaxo.Calc
Assembly: AltaxoCore (in AltaxoCore.dll) Version: 4.8.3179.0 (4.8.3179.0)
Syntax
C#
Copy
public static bool IsSmaller(
	this double a,
	double b,
	int decimalPlaces
)

Parameters

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

Return Value

Boolean
true if the first value is smaller than the second value; otherwise false.

Usage Note

In Visual Basic and C#, you can call this method as an instance method on any object of type Double. 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 thdecimalPlacesg. if decimalPlaces == 2, then 0.01 will equal between 0.005 and 0.015, but not 0.02 and not 0.00
