## Usage

```javascript
var realmin = require( '@stdlib/utils/real-min' );
```

#### realmin( dtype )

Returns the smallest positive **normal** value capable of being represented by a numeric **real** type.

```javascript
var m = realmin( 'float64' );
// returns 2.2250738585072014e-308
```

The following numeric **real** types are supported:

-   `float64`: double-precision floating-point numbers
-   `float32`: single-precision floating-point numbers
-   `float16`: half-precision floating-point numbers
