Correct conversion of float to string

[khanxmetu]

Hi, The difference in float and Decimal floating point representations may lead to discrepancies when converting from one type to another. Here is an excerpt from https://docs.python.org/3/library/decimal.html#module-decimal:

If value is a float, the binary floating-point value is losslessly converted to its exact decimal equivalent. This conversion can often require 53 or more digits of precision. For example, Decimal(float('1.1')) converts to Decimal('1.100000000000000088817841970012523233890533447265625').

Therefore it is best to directly convert float type to string.
