Luckily for you, Python offers a few functions that let you round numbers. Rounding numbers to two decimal places is common. Money only uses two decimal places; you do not want to process a monetary value with a third decimal place. Weights are often represented with two decimal places; ...
Adecimal place signifies the position right to the decimal point in the number line. Users can specify a value such as tenths, hundredths, etc. place values based on the position of the digits.A number contains two parts, a whole number part, and a fractional part. The place value of :...

There is also a need to define where we are going to perform the rounding (we could truncate, but rounding seems statistically fairer). It could be done in the _samples functions of the classes defined in core.py, but maybe there is a better place. Thanks for reading.Member...

A. For some values, exponential notation is the only way to express the number of significant places in the coefficient. For example, expressing 5.0E+3 as 5000 keeps the value constant but cannot show the original’s two-place significance....
So, in summary: there are many reasons why people need or want to preserve both the exponent (scale) of a number (which defines the units of the last place) and the precision of the integral number of those units which represents a particular value an arithmetic processor cannot determine...
