Optimizer inputC parameter - integer vs float

[dragoshenron]

Among other values, the optimizers are reporting input voltage (inputV) and input current (inputC), i.e. module voltage/current.
This is an example of what I get:
optimizer { serialNumber: "21211D16-75" online: true lastReport { year: 2019 month: 10 day: 5 hour: 13 minute: 18 second: 18 } outputV: 48 inputV: 31 inputC: 4 temperature { value: 26 } }

Now, current is shown only as 4(Amps), while on the website is reported 4.4375.
Is there something wrong in the visualisation format, e.g. integer vs float?
