Dear All,
I need one help.
In python, I need to set the floating point precision as 2.
I am getting the following output in python while adding two float nos.
>>>a=79.73
>>>b=0.5
>>> a+b
80.230000000000004
I need exactly 2 precision point in this float value. i.e. 80.23
Even though I tried in round method, its not satisfied me. Because
>>> a = round(3.7138464897123424324355124355,2)
>>> a
3.71
>>> a = round(3.7238464897123424324355124355,2)
>>> a
3.7200000000000002
Can you understand the difference. Depends upon the value, it will round.
I no need ceil and floor options. Because it may change the original values.
I need just 2 precision point in the float value.
I am getting two numbers dynamically. So I can not say exactly, what kind of
floating numbers I am going to use.
What I have to do ?
Any suggestions ?
Thanks in advance.
