Scientific Notation for Inputs | enhancement

[Randall-Scharpf]

Description

While extremely large numbers (like the mass of the sun), are output in metric using scientific notation, inputs are not recognized as scientific notation and instead must be directly entered as a decimal.

This shows the method by which an input must be given in order to elicit a conversion. However, since no right-minded person would text the mass of the sun over Discord in such a way, we should expect never to make such a conversion. Instead, we should expect to find scientific notation.

Example Failure Cases

• The form A.BCeD
  
• The form A.BCe+D
  
• The form A.BC*10^D
  
• The form A.BC*!0^+D
  

Other similar forms exist and can (and perhaps should) be supported.

Proposed Solutions

• Expand the regex for finding numbers, and add any addition "pythonizing" between the string catching and float conversion (current "pythonizing" consists of a forced conversion from the comma to the period as radix)
• Import a library for parsing numbers from strings

Potential Related Issues

• No idea what sort of licensing requirements or such would come with adding a library
