| Formula | Description | Result | Expected | Verdict |
|---|---|---|---|---|
| =PI() | PI() takes no arguments and returns the double-precision approximation of pi | 3.14159265358979 | 3.141592653589793 | Matched |
| =ROUND(PI(),4) | Common real-world usage: rounding PI() to a fixed number of decimals | 3.1416 | 3.1416 | Matched |
| =PI()*2 | PI() used directly in arithmetic (e.g. computing a full turn in radians) | 6.28318530717959 | 6.283185307179586 | Matched |
