IsCountableSequence(IEnumerable<Int32>)

Determines whether the specified source is a sequence of countable integrals (hence, integrals being either incremented or decremented with the same cardinality through out the sequence).

Declaration

public static bool IsCountableSequence(this IEnumerable<int> source)

Parameters

Type	Name	Description
System.Collections.Generic.IEnumerable<System.Int32>	source	The value to test for a sequence of countable characters.

Returns

Type	Description
System.Boolean	`true` if the specified `source` is a sequence of countable integrals (hence, integrals being either incremented or decremented with the same cardinality through out the sequence); otherwise, `false`.

Parameters

Type	Name	Description
System.Collections.Generic.IEnumerable<System.Int64>	source	The value to test for a sequence of countable characters.

Returns

Type	Description
System.Boolean	`true` if the specified `source` is a sequence of countable integrals (hence, integrals being either incremented or decremented with the same cardinality through out the sequence); otherwise, `false`.

RoundOff(Double, RoundOffAccuracy)

Rounds a double-precision floating-point value to the nearest integral value closest to the specified accuracy.

Declaration

public static double RoundOff(this double value, RoundOffAccuracy accuracy)

Parameters

Type	Name	Description
System.Double	value	A double-precision floating-point number to be rounded.
RoundOffAccuracy	accuracy	The accuracy to use in the rounding.

Returns

Type	Description
System.Double	The integer value closest to the specified `accuracy` of `value`. Note that this method returns a System.Double instead of an integral type.
