Show two digits after decimal point in c++
Similar topic is already discussed in the forum. But I have some different problem in following code: If I give input as 100.00 then program prints just 100 but not 100.00 How can I print 100.00?

I want a to be rounded to 13.95. The round function does not work the way I expected.
Double precision floating values in Python?
Decimal datatype Unlike hardware based binary floating point, the decimal module has a user alterable precision (defaulting to 28 places) which can be as large as needed for a given problem. If you are pressed by performance issuses, have a look at GMPY

What is the difference between float and double?
Huge difference. As the name implies, a double has 2x the precision of float[1]. In general a double has 15 decimal digits of precision, while float has 7. Here’s how the number of digits are calculated: double has 52 mantissa bits + 1 hidden bit: log(253)÷log(10) = 15.95 digits float has 23 mantissa bits + … Read more
