May 24, 2021Why does round(2.35, 1) return 2.4 (rounded up) but round(2.25, 1) returns 2.2 (rounded down)?
It’s a rounding method to balance error. If you always round up, it creates unbalanced weighting towards increasing. The idea is the digit in front of the 5 dictates the direction, odd rounds up while even rounds down. More on reddit.com

You generally don't round until you go to display the value. You can use round for that, but since you just want to display it with two digits, you can use string formatting . In your case, something like print(f'{totalPay:.2f}'). .2f is the format specifier, saying round the float (f) to two decimal places (.2). More on reddit.com

In accordance with standard rounding procedures in financial computations, ROUND_HALF_UP guarantees that numbers precisely halfway between two values round up to the larger value, while Decimal(‘0.01’) indicates that we wish to round to cents. In addition to the decimal module, for controlling numerical precision, Python offers string formatting. We will explore different string formatting methods, including f-strings, str.format(), and the % .2f approach, and discuss them in detail in the next section.

The float printing routines use an accurate but much more computationally demanding algorithm to compute the number of digits after the decimal point. Alternatively, Python’s builtin round function uses a more accurate but slower algorithm for 64-bit floating point values: >>> round(56294995342131.5, 3) 56294995342131.5 >>> np.round(16.055, 2), round(16.055, 2) # equals 16.0549999999999997 (16.06, 16.05)
