Int32::CompareTo Method (Int32)
Compares this instance to a specified 32-bit signed integer and returns an indication of their relative values.
Assembly: mscorlib (in mscorlib.dll)
Parameters
- value
- Type: System::Int32
An integer to compare.
Return Value
Type: System::Int32A signed number indicating the relative values of this instance and value.
Return Value | Description |
|---|---|
Less than zero | This instance is less than value. |
Zero | This instance is equal to value. |
Greater than zero | This instance is greater than value. |
Implements
IComparable<T>::CompareTo(T)This method implements the System::IComparable<T> interface and performs slightly better than the Int32::CompareTo method because it does not have to convert the value parameter to an object.
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, 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.
