modbus_set_float(3) Manual Page

void modbus_set_float(float f, uint16_t *dest);

Warning, this function is deprecated since libmodbus v3.2.0 and has been replaced by modbus_set_float_dcba().

The modbus_set_float() function shall set a float to 4 bytes in Modbus format (ABCD). The dest array must be pointer on two 16 bits values to be able to store the full result of the conversion.

There is no return values.
