How do I pass floats to opencl (via the PyOpenCL API) and return python floats?

[Jory R Ferrell]

I am using PyOpenCL. I pass a array of floats to the OpenCL kernel. When the floats are returned, python can't use the types C types and has strange values:8.275480 23e-36 8.27548310e-36, etc.

float myFunc(float number, float iter_val)
{
float output;
// Beginning of FOR loop #1
for(0;iter_val-1>0;){
                     
                     
                     if(output == 0){
                                     output = number*number;
                                     iter_val = iter_val - 1;
                                     }
                                     
                     else{          
                          output = output*number;
                          iter_val = iter_val - 1;
                          }
                          
                     } // End of FOR loop #1

return output;
} //End of myFunc definition
                                        
                                        
// Main Kernel //
                                        
__kernel void part1(__global float* a, __global float* b, __global float* c)
{
    
    unsigned int i = get_global_id(0);

    c[i] = myFunc(a[i], b[i]);
