Converting 32 bit Floating Point, and 48 and 64 bit Integer to string

[richard]

you have not really explained what format the serial data input takes . can you provide a few examples of input data verses desired result

I can try to explain. I get 4 bytes for FP.
Eg:
For temperature 23.75, I get 4 bytes $41,$BE,$00,$00
24.375=$41,$c3,$00,$00
etc...
And that values matches with results from this calculator:
