| Fixed-Point Toolbox™ | |
The properties associated with fipref objects are described in the following sections in alphabetical order.
Data type override options for fi objects
ForceOff — No data type override
ScaledDoubles — Override with scaled doubles
TrueDoubles — Override with doubles
True Singles — Override with singles
Data type override only occurs when the fi constructor function is called.
The default value of this property is ForceOff.
Display options for the fimath attributes of a fi object
full — Displays all of the fimath attributes of a fixed-point object
none — None of the fimath attributes are displayed
The default value of this property is full.
Logging options for operations performed on fi objects
off — No logging
on — Information is logged for future operations
Overflows and underflows for assignment, plus, minus, and multiplication operations are logged as warnings when LoggingMode is set to on.
When LoggingMode is on, you can also use the following functions to return logged information about assignment and creation operations to the MATLAB® command line:
maxlog — Returns the maximum real-world value
minlog — Returns the minimum value
noverflows — Returns the number of overflows
nunderflows — Returns the number of underflows
LoggingMode must be set to on before you perform any operation in order to log information about it. To clear the log, use the function resetlog.
The default value of this property of off.
Display options for the numerictype attributes of a fi object
full — Displays all the numerictype attributes of a fixed-point object
none — None of the numerictype attributes are displayed.
short — Displays an abbreviated notation of the fixed-point data type and scaling of a fixed-point object in the format xWL,FL where
x is s for signed and u for unsigned.
WL is the word length.
FL is the fraction length.
The default value of this property is full.
Display options for the value of a fi object
bin — Displays the stored integer value in binary format
dec — Displays the stored integer value in unsigned decimal format
RealWorldValue — Displays the stored integer value in the format specified by the MATLAB format function
hex — Displays the stored integer value in hexadecimal format
int — Displays the stored integer value in signed decimal format
none — No value is displayed.
The default value of this property is RealWorldValue. In this mode, the value of a fi object is displayed in the format specified by the MATLAB format function: +, bank, compact, hex, long, long e, long g, loose, rat, short, short e, or short g. fi objects in rat format are displayed according to
