double word not shown correct

[starfish1107]

hello
your little prg promised to be useful for reading data from modbus using zabbix but some values consist of double word length so only hex and some calculation shows reasonable data.
example
-n2 to show 2 registers
with option r3 or r4 I get 00003;20708 which makes no sense
hex option shows 0x003 and 0x4EF0 which is concatenated 0x0034EF0 this is the correct data.
is there a way to get the correct data in decimal or float from mbtget? or could you built in this option?
