dimensions_and_type_from_string
(unit_string)[source]¶ Returns the physical dimensions that results from evaluating a string like “siemens / metre ** 2”, allowing for the special string “1” to signify dimensionless units, the string “boolean” for a boolean and “integer” for an integer variable.
Parameters: unit_string : str
The string that should evaluate to a unit
Returns: d, type : (
Dimension
, {FLOAT, INTEGER or BOOL})The resulting physical dimensions and the type of the variable.
