--- Comment #9 from Sergei Gavrikov <sergei.gavrikov@gmail.com> 2012-08-14 08:41:03 BST ---
Created an attachment (id=1895)
 --> (http://bugs.ecos.sourceware.org/attachment.cgi?id=1895)
printf() zero-padding issue fix

And may be just to expand a set of the arguments the cvt()? See the patch.

Then this

  printf("%g %- 30.18e\n", 3.14e-11, 3.14e-11);
  printf("%g %- 30.18f\n", 3.14e-11, 3.14e-11);

will output

  3.14e-11  3.140000000000001000e-11
  3.14e-11  0.000000000031400000
