# `Benchee.Conversion.DeviationPercent`
[🔗](https://github.com/bencheeorg/benchee/blob/1.5.1/lib/benchee/conversion/deviation_percent.ex#L1)

Helps with formatting for the standard deviation ratio converting it into the
more common percent form.

Only Benchee plugins should use this code.

# `format`

Formats the standard deviation ratio to an equivalent percent number including special signs.

The ± is an important part of it as it shows that the deviation might be up but also might be
down.

## Examples

    iex> format(0.12345)
    "±12.35%"

    iex> format(1)
    "±100.00%"

# `format_human`

Formats standard deviation percent, same as `format/1`.

Implemented for consistency.

## Examples

    iex> format_human(0.1)
    "±10.00%"
