modbus_get_float(3) Manual Page

float modbus_get_float(const uint16_t *src);

Warning, this function is deprecated since libmodbus v3.2.0 and has been replaced by modbus_get_float_dcba().

The modbus_get_float() function shall get a float from 4 bytes in Modbus format (DCBA byte order). The src array must be a pointer on two 16 bits values, for example, if the first word is set to 0x4465 and the second to 0x229a, the float value will be 916.540649.

The function shall return a float.
