# This Python code is a simple sample that provides a Python implementation of 
# the Divide Service used in the Calculator sample
# 
# Either use the divide function in the DivideClass class (using classes allows 
# composite scoping to be used)
# e.g. in CalculatorComposite.composite use the line:
#   <implementation.python module="DivideImpl" class="DivideClass"/>
# 
# Or just use the module-level divide function
# e.g. in CalculatorComposite.composite use the line:
#   <implementation.python module="DivideImpl" />
#

    "A class to handle dividing"

    def __init__(self):

    # The class-level divide function
    def divide(self, val1, val2):
        result = float(val1) / float(val2)

        print "Python - DivideImpl.DivideClass.divide " + str( val1 ) + " / " + str(val2) + " = " + str(result)

        # Use the doRounding property
        if doRounding:
           result = round(result)
           print "Python - DivideImpl.DivideClass.divide is rounding the result to " + str(result)
