Hi. Why i get the error of the title.

Test case:

$p = BigDecimal::of(1.54);

print_r(BigDecimal::of(100)->dividedBy($p, RoundingMode::HALF_UP));

Solved setting the precision in this way

$p = BigDecimal::of(1.54);
$precision = 2;

print_r(BigDecimal::of(100)->dividedBy($p, $precision, RoundingMode::HALF_UP));

If there is no other ways to do, the we can close the issue.

Hi, indeed, the rounding mode is the 3rd parameter, the 2nd being the precision! :+1:
