  2. ========================
  3. NAME
  4. ----
  5. modbus_get_float_dcba - get a float value from 2 registers in DCBA byte order
  6. SYNOPSIS
  7. --------
  8. *float modbus_get_float_dcba(const uint16_t *'src');*
  9. DESCRIPTION
  10. -----------
  11. The *modbus_get_float_dcba()* function shall get a float from 4 bytes in
  12. inversed Modbus format (DCBA order instead of ABCD). The _src_ array must be a
  13. pointer on two 16 bits values, for example, if the first word is set to 0x47F1
  14. and the second to 0x2000, the float value will be read as 123456.0.
  15. RETURN VALUE
  16. ------------
  17. The function shall return a float.
