Usage

• In order to use SetPrecision, start by importing the module to your Python environment:

  from SetPrecision import set_precision
  

• Now, simply call the set_precision method and enter your desired number to be formatted as the number parameter, and the level of precision as the precision parameter:

  >>> testA = 3.141592653589793 # Not necessary to set number as variable.
  
  >>> testA = set_precision(testA, 2)
  
  >>> print(testA)
  
  '3.15'
  
  >>> testB = 3.141592653589793
  
  >>> testB = set_precision(testB, 4)
  
  >>> print(testB)
  
  '3.1416'
  

Note that the output is automatically rounded up when number >= 5, and down when number < 5.

• Both params can be entered in string format, and will output successfully assuming that both parameters can be cast to their appropriate types.
  • This is done automatically.
