fixFloatingPoint(self, number)

source code

This function addresses the floating point representation in Python It takes a float or double and turns it into its fixed representation. i.e. 0.01 is represented as 1.0000000475 or 1.00000001 depending on the hardware The function will return 0.01; the precision used is 1/100 000

getPythonFormat(self, mapped_type, mapped_endianness)

source code

In the XML map schema the data types are named after C conventions i.e. 2 byte integers are 'int16' This function returns the Python data type.
