# std::ratio_less_equal

From cppreference.com
< cpp‎ | numeric‎ | ratio

Defined in header `<ratio>` |  |
template< class R1, class R2 > struct ratio_less_equal : std::integral_constant; |  |

If the ratio `R1` is less than or equal to the ratio `R2`, provides the member constant `value` equal true. Otherwise, `value` is false.

### [edit] Helper variable template

template< class R1, class R2 > inline constexpr bool ratio_less_equal_v = ratio_less_equal<R1, R2>::value; |  | (since C++17)

[edit]

## Inherited from std::integral_constant

### Member constants

value [static] | true if R1::num * R2::den <= R2::num * R1::den, or equivalent expression that avoids overflow , false otherwise (public static member constant)

### Member functions

operator bool | converts the object to bool, returns `value` (public member function)
operator() (C++14) | returns `value` (public member function)

### Member types

Type | Definition
`value_type` | `bool`
`type` | std::integral_constant<bool, value>
