get a float value from 2 registers in CDAB byte order


float modbus_get_float_cdab(const uint16_t *src);


The modbus_get_float_cdab() function shall get a float from 4 bytes with swapped words (CDAB order instead of ABCD). The src array must be a pointer on two 16 bits values, for example, if the first word is set to F147 and the second to 0x0020, the float value will be read as 123456.0.

Return Value

The function shall return a float.
