The \fIsrc\fR 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\&. .SH "RETURN VALUE" .sp The function shall return a float\&. .SH "SEE ALSO" .sp \fBmodbus_set_float\fR(3) \fBmodbus_set_float_dcba\fR(3) \fBmodbus_get_float_dcba\fR(3) .SH "AUTHORS" .sp The libmodbus documentation was written by Stéphane Raimbault
