UInt64.CompareTo Method (UInt64)
Compares this instance to a specified 64-bit unsigned integer and returns an indication of their relative values.
Assembly: mscorlib (in mscorlib.dll)
- Type: System.UInt64
An unsigned integer to compare.
Return ValueType: System.Int32
A signed number indicating the relative values of this instance and value.
Less than zero
This instance is less than value.
This instance is equal to value.
Greater than zero
This instance is greater than value.
Depending on your programming language, it might be possible to code a CompareTo method where the parameter type has fewer bits (is narrower) than the instance type. This is possible because some programming languages perform an implicit widening conversion that represents the parameter as a type with as many bits as the instance.
For example, suppose the instance type is Int32 and the parameter type is Byte. The Microsoft C# compiler generates instructions to represent the value of the parameter as an Int32 object, then generates a Int32.CompareTo method that compares the values of the Int32 instance and the Int32 parameter representation.
Consult your programming language's documentation to determine whether its compiler performs implicit widening conversions on numeric types.
