Print float on a vector

[Gui_STM]

Good afternoon,

I am testing my UART and using a vector to store float numbers as shown below:

 

raptor::std::vector<float> numbers;

  numbers.append(3.14f);

  numbers.append(2.21f);

  numbers.append(1.01f);

  numbers.append(8.15f);

  numbers.append(0.05f);

Here is how I am inserting float numbers into my vector. However, when I try to print them using:

    for(int i = 0; i < 5; i++)

      printf("%f ", numbers[i]);

Everything after the second number prints as 0. Below is an example of the output from my UART:

3.140000 2.210000 0.000000 -nan 0.000000

Can someone help me with this issue, please?

May be memory allocation does not work properly. It happens under the covers when c++ objects are constructed. Debug and look at the addresses of your c++ objects.

Ok, I will try to see where in the address is the bug.
