Posting images of code is not very good. Posting snippets of code is not very good. Read the forum guidelines to see how to properly post code and some hints on how to get the most from this forum.
Use the IDE autoformat tool (ctrl-t or Tools, Auto format) before posting code in code tags.
The quickest way to get help is to post a minimal verifiable code that exhibits the problem.
If you want to print more (or less) than 2 decimal places use (see the print reference):
Serial.print(floatNumber, decimal_places);
like
Serial.print(AcX1,4); // prints 4 decimal places
Floats in Arduino are only 6 significant digits so are not as accurate as you may want.
From the reference on the float data type.
The float data type has only 6-7 decimal digits of precision. That means the total number of digits, not the number to the right of the decimal point. Unlike other platforms, where you can get more precision by using a double (e.g. up to 15 digits), on the Arduino, double is the same size as float.
