bf_find_root precision warnings




when I run this script:

kill(all)$
fpprec:32$
float2bf:false$
y: x/sin(x)-5281/5280$
bf_find_root(y,x,1/100,4/100);


I get several of these warnings:

bfloat: converting float 0.10000000000000001 to bigfloat.

Is there a way to format the problem so that I get true bigfloat precision?
