  5. modbus_get_float_abcd - get a float value from 2 registers in ABCD byte order
  6. SYNOPSIS
  7. --------
  8. *float modbus_get_float_abcd(const uint16_t *'src');*
  9. DESCRIPTION
  10. -----------
  11. The *modbus_get_float_abcd()* function shall get a float from 4 bytes in usual
  12. Modbus format. The _src_ array must be a pointer on two 16 bits values, for
  13. example, if the first word is set to 0x0020 and the second to 0xF147, the float
  14. value will be read as 123456.0.
