Sample temp sensor does not compile

[joeatbayes]

In File: https://github.com/epsilonrt/modbus-serial/blob/master/examples/TempSensor/TempSensor.ino on Line #53 it shows:
mb.Ireg (SensorIreg, analogRead (SensorPin));

This is inconsistent with header defined in the header file that shows that function accepting a single parameter. I think you need ** mb.setIreg(SensorIreg, reading);**

Also where can I find more data on exchanging 32 bit floats?
