Find min and max value in a float array

// Find min and max value in a float array
void find_min_max(int size, const float *data, float *min, float *max)
{
    *min = *max = data[0];
    for (int i = 0; i < size; i++)
    {
        const float val = data[i];
        *min            = std::min(*min, val);
        *max            = std::max(*max, val);
    }
}

// Return reasonable quantisation parameters to use for an array of floats
// based on min and max values
