The problem of floating point approximating numbers that are not exact
powers of 2 remains the problem, regardless of how your chosen language
handles it.

$ echo "scale=50; 1/10+2/10"|bc
.30000000000000000000000000000000000000000000000000

$ awk 'BEGIN{printf("%.40f\n",1/10+2/10)}'
0.3000000000000000444089209850062616169453
