Issue with imread. Strange float values - c++

Question

I'm trying to simple load an image (TIFF) and display a pixel value.
If I open the image using ImageJ the values are 32-bit float. But opening the same image using opencv I get really strange float values, e.g. 4.2039e-44.
If I read the value of a specific pixel using "int" the presented value is correct. Below is the code I use to test. And here a link for the image: https://goo.gl/Wmv9xE.
Thanks in advance.
#include <opencv2/highgui/highgui.hpp>
#include <opencv2/core/core.hpp>
#include <iostream>
int main(int argc, char **argv) {
std::string imageFile = "image.tiff";
cv::Mat image;
image = cv::imread(imageFile, CV_LOAD_IMAGE_ANYDEPTH); // Read the file
if (!image.data) // Check for invalid input
{
std::cout << "Could not open or find the image: " << imageFile << std::endl;
return -1;
}
std::cout << "Image:" << image.rows << " x " << image.cols << " Channels: " << image.channels() << " Depth: " << image.depth() << std::endl;
std::cout << "Value at 0,0: " << image.at<float>(0,1)<< std::endl; // Strange Value
std::cout << "Value at 0,0: " << image.at<int>(0,1)<< std::endl; // Correct Value
return (EXIT_SUCCESS);
}
* Update *
Trying to move forward with the code, I decided to create a function to convert the data to "int" reading from the file.
As a temporary solution this worked, but I'm still looking for the reason why the data is being loaded wrong.
int main(int argc, char **argv) {
std::string imageFile = "/home/slepicka/XSConfig/image.tiff";
cv::Mat image = openImage(imageFile);
if (!image.data) // Check for invalid input
{
std::cout << "Could not open or find the image: " << imageFile << std::endl;
return -1;
}
std::cout << "Image:" << image.rows << " x " << image.cols << " Channels: " << image.channels() << " Depth: " << image.depth() << " Type: " << image.type() << std::endl;
std::cout << "Value at 0,0: " << image.at<int>(0,1)<< std::endl; // Correct Value
//std::cout << "Data: " << image << std::endl;
return (EXIT_SUCCESS);
}
cv::Mat openImage(std::string filename){
cv::Mat imageLoad = cv::imread(filename, CV_LOAD_IMAGE_ANYDEPTH);
if(imageLoad.type() == CV_32F){
return convertToInt(imageLoad);
}
return imageLoad;
}
cv::Mat convertToInt(cv::Mat source){
int r, c;
cv::Mat converted;
converted.create(source.rows, source.cols, CV_32SC1);
for (r=0; r<source.rows;r++) {
for (c=0; c<source.cols;c++) {
converted.at<int>(r, c) = source.at<int>(r, c);
}
}
return converted;
}
