Inconsistencies in reading .dat file during run time in new injection model

Hello everyone!
I'm trying to create a new injection model called myPatchInjection in OpenFOAM. Now, what this model should ideally do is read the time values from a .dat file and if this value matches with the current run time value, inject the corresponding number of particles (read from another column in the .dat file) from a predefined patch. Now, my injection model is reading the values from the .dat file. The problem that I'm facing is that when I compare this value with the actual run time value, it shows some inconsistencies. Here's a small snippet of the output log file that I've generated. Code:

2 I think the problem lies in the if statement where I'm comparing the times. Possibly, it can also be a case of data type mismatch. This is proving a real roadblock in the work that I'm doing currently. Maybe, its an OpenFOAM bug. I don't know.. The testing.zip file contains the kinematic cloud properties file, the system folder and constant directory. It however does not contain the polyMesh folder or the .msh file due to size constraints that limits the size of the zip file. A simple mesh with boundary zones including INLET, OUTLET and PART_1 can be created to match the zone names that I had while running the case so that no changes to other files would be required. If you choose to run your own mesh, then please change the part names in all the files in the zero folder. Any help is greatly appreciated. The model has been compiled on OpenFOAM v1706. There are slight changes in the header files that need to be made if you're using OF 3.0 or earlier.
