Hi all,

I have not found that in the library.

Here is the implementation.

double roundd ( double n, int decimals )
{
double p = ipow10 ( decimals );
return floor ( n*p + 0.5 ) / p;
}

A.

Hi Aftershock,

It is not in the library, but you exactly reinvented what is written in documentation Very Happy

See About rounding double values.
