Due to the quirks of floating point representation, these rounded values may be slightly off. given 3.14159, it will output .14159 I do not know the %f for only showing the decimal part of the number the user enters. So as I was using an LCD anyway I thought I'd just use that for debugging, however, lcd.print(float value) doesn't seem to work either. Or even just use a float format specifier to specify getting a string with no decimal places. It is a 32-bit IEEE 754 single precision floating point number ( 1-bit for the sign, 8-bit for exponent, 23*-bit for the value. You can read about it in the official documentation here. First is the number to be rounded. It has 6 decimal digits of precision. In this tutorial, learn how to limit float to two decimal places in Python. The printf("%.2f") approach is the correct one to use, but it will round up to 9.84, so it depends on how serious you are about getting 9.83.

By default, the Serial print function shows only 2 decimals, however I'm sure the float has the full (unrounded) value, even if it does not show it. This is a very basic article that will explain a few ways of restricting a decimal value to 2 decimal places in C#. (See Standard Numeric Format Strings). e.g. Second argument decides the number of decimal places to which it is rounded. Consider the given code, here we have a float variable named num and its value is "10.23456".
