# denormalmin

Smallest denormalized quantized number for `quantizer` object

## Syntax

`x = denormalmin(q)`

## Description

`x = denormalmin(q)` is the smallest positive denormalized quantized number where `q` is a `quantizer` object. Anything smaller than `x` underflows to zero with respect to the `quantizer` object `q`. Denormalized numbers apply only to floating-point format. When `q` represents a fixed-point number, `denormalmin` returns `eps(q)`.

## Examples

```q = quantizer('float',[6 3]); x = denormalmin(q) x = 0.0625 ```

### Algorithms

When `q` is a floating-point `quantizer` object,

$x={2}^{{E}_{min}-f}$

where Emin is equal to `exponentmin(q)`.

When `q` is a fixed-point `quantizer` object,

$x=\mathrm{eps}\left(q\right)={2}^{-f}$

where f is equal to `fractionlength(q)`.
