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 :

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
