I am using Python for calculations.
However, I faced the inaccuracies in calculations.
Thus, 0.7+0.1=0.79999, etc. (float)
May anyone suggest a way for exact calculations?

Which version of python are you running? You can round the number using the function round() – almanegra Apr 12 '17 at 12:02

No, I need precision E-11 – Sonya Seyrios Apr 12 '17 at 12:03

3That's not what it should be marked as duplicated of. It sounds more like OP is searching for `Decimal("0.7") + Decimal("0.1")` which would correctly result in `0.8`. – vallentin Apr 12 '17 at 12:04

Yes, but I have to write Decimal() everywhere! For all variables, and for operations over them. – Sonya Seyrios Apr 12 '17 at 12:04

I don't at all see the problem. You equally have to use a keyboard to be able to type on a computer. That's not an inconvenience. – vallentin Apr 12 '17 at 12:05

Ok, I'll try... – Sonya Seyrios Apr 12 '17 at 12:06

Why in c=Decimal(a)*Decimal(b) the variable c is not Decimal? – Sonya Seyrios Apr 12 '17 at 12:07

Maybe it helps you `round(0.7+0.1, 11)`. This produces 0.8. – Roman Alexeev Apr 12 '17 at 12:11
