Hello eveyone,
I am a second year student of Indian Institute of Technology, Ropar. I am
quite comfortable with c, c++, HTML, CSS, javaScript and java programming.
I am new in the open source software community and wish to contribute in
free software. I have found out about the FFmpeg community f
avoids the float to integer cast, and is slightly superior in terms of
rounding ("Dutch/Gauss rounding").

This tightens the errors by doing a first order Taylor approximation of
one obvious source of error. This results in negligible runtime
slowdown, but improves worst case relative error by ~ 30%, worst case
ulp count from 673 to 391. Another illustration is:
arg : -303.13720760010643270798027
Fast, reasonably accurate 10^x. Alternative of detection of libm exp10 at
configure
time is not worth the trouble, since it is anyway not POSIX or ISO C,
and currently only the GNU libm has it. Furthermore, GNU libm's variant
is ~ 2x slower, and is ironically not correctly rounded (2 ulp off) to j
