.SH "NAME"
modbus_get_float \- get a float value from 2 registers
.SH "SYNOPSIS"
.sp
\fBfloat modbus_get_float(const uint16_t *\fR\fB\fIsrc\fR\fR\fB);\fR
.sp
Warning, this function is \fBdeprecated\fR since libmodbus v3\&.2\&.0 and has been replaced by \fBmodbus_get_float_dcba()\fR\&.
.SH "DESCRIPTION"
.sp
The \fBmodbus_get_float()\fR function shall get a float from 4 bytes in Modbus format (DCBA byte order)\&. 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\&.
