>>> x = "2342.34"
>>> float(x)
2342.3400000000001
There you go. Use float (which behaves like and has the same precision as a C,C++, or Java double).
Be aware that if your string number contains more than 15 significant digits float(s)
will round it.In those cases it is better to use Decimal
Here is an explanation and some code samples: https://docs.python.org/3/library/sys.html#sys.float_info
>>> x = "2342.34"
>>> float(x)
2342.3400000000001
There you go. Use float (which behaves like and has the same precision as a C,C++, or Java double).
The decimal operator might be more in line with what you are looking for:
>>> from decimal import Decimal
>>> x = "234243.434"
>>> print Decimal(x)
234243.434
>>> x = "2342.34"
>>> float(x)
2342.3400000000001
There you go. Use float (which behaves like and has the same precision as a C,C++, or Java double).
