Try this: #include <stdio.h> int main() { double pi = 3.14159265358979323846 ; printf("%20.19f\n", pi); } and here is what you get: host: [16:45] [127] /tmp>./test 3.1415926535897931160 The error in last 4 or digits is obvious. It seems that the culprit is __dtoa which incorrectly turns double precision numbers into strings. This is on FreeBSD 4.3 release..
