msg file float variable digit problem
- OS: Ubuntu 16.04 LTS with 4.15.0-52-generic kernel
- ROS version: Kinetic
Hello, I'm writing a node for Pepperl+Fuchs PGV100.
You can check it out on it's github page.
I have a message file like this,
my.msg
Header header
float32 angle
uint64 x_pos
float32 y_pos
string direction
uint8 color_lane_count
uint8 no_color_lane
uint8 no_pos
The output like this. The angle looks like has a one digit but it is 0 always. But why ROS msg is not publishing this one also with 10 digit accuracy.
angle: 314.0
x_pos: 11
y_pos: -19.6000003815
direction: "Straight ahead"
color_lane_count: 0
no_color_lane: 1
no_pos: 1
I want to publish my float messages with 2 digit after decimal. I'm writing the node in C++ and If it's nothing to do with ROS msg publishing, I'll try to fix the problem on my code.
Thanks!
Can you show us how you are populating the
anglefield? So: can you show the code that sets its value?I get the data from the Pepperl+Fuchs PGV100 as a string. I convert this string to the decimal with a unsigned long integer variable in the string2decimal function. Then, when I'm populating angle, I converted to degree by dividing to 10.0
y-pos is the same but the values that I got from the device are like this
angle: 3450 - for angle 345 degree y-pos: 72 - for 7.2 mm
When I change the angular resolution to 0.1 degree. It starts to give me with 10 digits like y-pos.
I'll add the code's github page to the question. But it's a quite dirty code with all of the communication settings.
what do you think? By the way, the code is pretty straight forward. Because I'm still learning programming.
