## Name
modbus_get_float - get a float value from 2 registers
## Synopsis
```c
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Warning, this function is *deprecated* since libmodbus v3.2.0 and has been
replaced by *modbus_get_float_dcba()*.
## Description
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.
## Return value
The function shall return a float.
