- map(func, dimensionless=True)[source]
apply a custom function to each value of the series
- Parameters
func (function) – a function mapping a scalar to another scalar
dimensionless (bool) – if set to True, the mapping function takes an argument of type Number (no unit, dimensionless). The resulting timestamp series will keep the original unit. If set to False, the mapping function takes an argument of type pint.Quantity. The resulting timestamp series will have the unit of the mapped values. Mapping values of one series to different units results in an error. Mapping with dimensionless=False will result in a loop and therefore perform slower.

- Parameters
value (float/int) – the value to prepend
- Returns

- Return type
- round(decimals)[source]
round the values of the series
- Parameters
decimals – no of decimal places to round to
- Returns
the series with rounded values
