Round up to 2 decimal places. Shadowranger mar 2 16 at 448. Say the function should round 234249 to 2 decimal places.
A decimal 10272. Luckily for you python offers a few functions that let you round numbers. Beginning with python 25.
Rounding numbers to two decimal places is common. The code then first multiplies 234249 with 100 10 2. Others operations like division and non integer multiplication will change the number of decimal places and need to be followed up with a quantize step.
Mathceil then rounds 234249 up to an integer 2343. The first argument is the float variable whose value you want to change or limit. From the above code we can see that 2f prints the value up to 2 decimal places ie basically rounding off the value of x.
In a fixed point application with two decimal places some inputs have many places and need to be rounded. The second argument is the number of decimal places you want to convert to. You can also achieve this result using string interpolation and formatting.
Finally we divide back with 100 to get the result in two decimal digits. The round is the commonly known function of python to perform this task. Share a link to this answer.
You do not want to process a monetary value with a third decimal place. Use the python round to change to 2 decimal places. You can also round float to 3 decimal places after the decimal point.
You can use string formatting to format floating point numbers to a fixed width in pythonfor example if you want the decimal points to be aligned with width of 12 characters and 2 digits on the right of the decimal you can use the following. Money only uses two decimal places. The docs you linked dont actually apply to based printf like formattingtheyre for the more powerfulflexible formatting with strformatthe strformat approach would be pi is 2fformat314159not better or worse in this case but strformat is extensible to user defined types.
