+_*(number)*_ Number base, default is `2`
 
 ### bits
-_***(boolean)***_ Enables `bit` sizes, default is `false`

-_***(number)***_ Specifies the SI suffix via exponent, e.g. `2` is `MB` for bytes, default is `-1`

+_*(boolean)*_ Enables long form of unit of measure, default is `false`
 
 ### output
-_***(string)***_ Output of function (`array`, `exponent`, `object`, or `string`), default is `string`

 ### standard
-_***(string)***_ Standard unit of measure, can be `iec` or `jedec`, default is `jedec`; can be overruled by `base`
