I read the data from the file, the data is like:
6336253000000,0,2.89729972727,0.499999869261,0.499999952934,-1.07080008367,0.499999869261,2.36749995293,0.499999916327,0,0.000789873880191,0.000378644598289,0.000136312062988,0.000242332550508,0.000378644598289,0.000136312062988,0.000242332550508,0,-1.14380808558,-0.548311212244,-0.197392069441,-0.350919208869,-0.548311212244,-0.197392069441,-0.350919208869,0,-6.13606402873,-14.2367822588,-11.0049472307,8.71407191407,1.00874062366,0.391059638015,-0.0348915901406,29.999309435
But when I use cout to output, they are like:
time:29.9993
--q_data---
2.8973 0.5 0.5 -1.0708 0.5 2.3675 0.5
--vel_data---

-6.13606 -14.2368 -11.0049 8.71407 1.00874 0.39106 -0.0348916
The percision is just 5 bit.
The way to set the percision
1. the percision after decimal point “.”
fixed: the percision after decimal point “.”
setprecision(n): how many bit of percision
cout<<fixed<<setprecision(10)<<q_data[i]<<" ";
show that:
time:30.0092674660

2. whole percision, including “.”
without fixed
cout<<setprecision(10)<<q_data[i]<<" ";
