printf("%lf") is not portable, so omit the "l".
The "l" (ell) width spec means something in the corresponding scanf usage,but not here. While modern POSIX says that applying "l" to "f" and otherfloating format specs is a no-op, SUSv2 says it's undefined. Buildfarmexperience says that some old compilers emit warnings about it, and atleast one old stdio implementation (mingw's "ANSI" option) actuallyproduces wrong answers and/or crashes.Discussion:https://postgr.es/m/21670.1526769114@sss.pgh.pa.usDiscussion:https://postgr.es/m/c085e1da-0d64-1c15-242d-c921f32e0d5c@dunslane.net
