The 3-decimals-only limit is there partly on purpose. :) The ECI API has
functions eci_command_float_arg() (variant of eci_command()) and
eci_last_float() to allow lossless exchange of float parameters. In C++
version you have the ECA_CONTROL::last_float() function.

But, but, I'm not against having a global control for float-to-string
precision. The current 3-digit precision is problematic especially for
saving/restoring chainsetup state.

Thanks, committed to CVS! I also added some text to ecasound(1) concerning
the new parameter.
