# [−] [src] Trait num_traits::ops::inv::Inv

    pub trait Inv {
        type Output;
        fn inv(self) -> Self::Output;
    }

Unary operator for retrieving the multiplicative inverse, or reciprocal, of a value.

## Associated Types

### `type Output`

The result after applying the operator.

Returns the multiplicative inverse of `self`.

# Examples

    use std::f64::INFINITY;
    use num_traits::Inv;

    assert_eq!(7.0.inv() * 7.0, 1.0);
    assert_eq!((-0.0).inv(), -INFINITY);

## Search Tricks

Prefix searches with a type followed by a colon (e.g., `fn:`) to restrict the search to a given type.

Accepted types are: `fn`, `mod`, `struct`, `enum`, `trait`, `type`, `macro`, and `const`.

Search functions by type signature (e.g., `vec -> usize` or `* -> vec`)

Search multiple things at once by splitting your query with comma (e.g., `str,u8` or `String,struct:Vec,test`)
