Trunc function with precision uses `round` instead of `trunc` semantics

[kumarUjjawal]

Describe the bug

The trunc function with a precision argument incorrectly uses rounding semantics instead of truncation.

When calling [trunc(value, precision)] where precision > 0, the function uses f64::round() internally instead of f64::trunc(), causing values to be rounded to the nearest digit rather than truncated towards zero.

To Reproduce

SELECT trunc(3.76, 1);

Expected behavior

Should be truncated towards zero instead of rounds to nearest.
