## System::operator<=(const T1\&, const Nullable\<T2\>\&) method


Determines if the specified value is less or equal to the value represented by the specified [Nullable](../nullable/) object by applying [operator<=()](./) to these values.

```cpp
template<typename T1,typename T2> std::enable_if<!IsNullable<T1>::value, bool>::type System::operator<=(const T1 &some, const Nullable<T2> &other)
```


| Parameter | Description |
| --- | --- |
| T1 | The type of the first comparand value |
| T2 | The underlying type of the [Nullable](../nullable/) object that represents the second comparand value |

| Parameter | Type | Description |
| --- | --- | --- |
| some | const T1\& | A constant reference to the value that is to be used as the first comparand |
| other | const Nullable\<T2\>\& | A constant reference to the [Nullable](../nullable/) object the represented value of which is to be used as the second comparand |

### ReturnValue

True if the first comparand is less or equal to the second comparand, otherwise - false

## System::operator* method


Returns a new instance of [Decimal](../decimal/) class that represents a value that is a result of multiplication of the specified value and the value represented by the specified [Decimal](../decimal/) object.

```cpp
template<typename T,typename _> Decimal System::operator*(const T &x, const Decimal &d)
```


| Parameter | Type | Description |
| --- | --- | --- |
| x | const T\& | The first multiplier |
| d | const Decimal\& | The [Decimal](../decimal/) object representing the second multiplier |

### ReturnValue

A new instance of [Decimal](../decimal/) class that represents a value that is a result of multiplication of **x** and the value represented by **d**.
