float modbus_get_float_cdab(const uint16_t *src);
Description
The modbus_get_float_cdab() function shall get a float from 4 bytes with
swapped words (CDAB order instead of ABCD). The src array must be a pointer on
two 16 bits values, for example, if the first word is set to F147 and the second
to 0x0020, the float value will be read as 123456.0.
