Methods

ApproximatelyEquals(Double, Double, Double)

Test if two values are approximately equal to each other with an optional tolerance value.

Declaration

public static bool ApproximatelyEquals(this double value, double other, double tolerance = 1E-05)

Parameters

Type	Name	Description
System.Double	value	The first value to test.
System.Double	other	The other value to test.
System.Double	tolerance	The threshold for equality. If not supplied, the global tolerance will be used.

Returns

Type	Description
System.Boolean	True if |other - value| < tolerance

MapBetweenDomains(Double, Domain1d, Domain1d)

Map/Scale a value from one domain to another. 3 mapped from (2,4) to (10, 20) would be 15.

Declaration

public static double MapBetweenDomains(this double value, Domain1d source, Domain1d target)

Parameters

Type	Name	Description
System.Double	value	The value to map.
Domain1d	source	The source domain to map from.
Domain1d	target	The target domain to map to.

Returns

Type	Description
System.Double

MapFromDomain(Double, Domain1d)

Map/Normalize a value from a domain to the domain (0,1).

Declaration

public static double MapFromDomain(this double value, Domain1d domain)

Parameters

Type	Name	Description
System.Double	value	The value to map
Domain1d	domain	The domain to map from.

Returns

Type	Description
System.Double	(value - domain.Min) / domain.Length

MapToDomain(Double, Domain1d)

Map/scale a value between 0-1 to a target domain. Will not reject values outside 0-1.

Declaration

public static double MapToDomain(this double value, Domain1d domain)

Parameters

Type	Name	Description
System.Double	value	The value to map.
Domain1d	domain	The domain to map to.

Returns

Type	Description
System.Double	value * domain.Length + domain.Min
