DisplayMode class Null safety
Display mode and a bit more. This selects between number base, float versus integer, and complex versus normal. The actual code is almost all concerned with formatting and display, but this is also a convenient place to select operations based on integer/float/complex mode.

Properties
- commaDistance → int
-
read-only
- displayName → String
-
How this mode is shown on the LCD display
read-only
- hashCode → int
-
The hash code for this object.
read-onlyinherited
- isFloatMode → bool
-
read-only
- radix → int
-
Put calculator in floating-point mode, displaying fractionDigits
read-only
- rightJustify → bool
-
Are digits right-justified in this mode? If not, they'll be
left-justified, like " 1.0 ".
read-only
- runtimeType → Type
-
A representation of the runtime type of the object.

Methods
-
addCommas(
String s, bool intToo) → String -
convertValuesTo(
DisplayMode next, Model< ProgramOperation> model) → void - Convert values in the model when switching between float and int, and vice-versa. We're switching from this mode to next. The 16C does interesting things with x and y here.
-
format(
Value v, Model< ProgramOperation> m) → String -
leastSignificantDigit(
double value) → int - Gives the least significant digit when value is displayed, where the units digit is 0, and negative is to the right of the decimal. For example, for FIX-3, gives -3 (10^-3 is 0.001), unless the value is such that scientific notation would be used.
-
noSuchMethod(
Invocation invocation) → dynamic -
Invoked when a non-existent method or property is accessed.
inherited
-
round(
Value x) → Value -
select<
R, A> (DisplayModeSelector< R, A> selector, A arg) → R - Select something based on whether we're in an int mode or a float mode.
-
setComplexMode(
Model< ProgramOperation> m, bool v) → void -
signMode(
IntegerSignMode integerSignMode) → SignMode - Give the calculator's effective sign mode, considering the current display mode (which might be float), and the sign mode that was last set when the calculator was in integer mode (which might be now).
-
toJson(
) → String -
toString(
) → String -
A string representation of this object.

tryParse(
String s, NumStatus m) → Value?
Operators
-
operator ==(
Object other) → bool -
The equality operator.

fix(
int fractionDigits, bool complex) → DisplayMode -
float(
int fractionDigits) → DisplayMode - digits after the decimal point. If digits is 10, always display in scientific notation, as per the 16C manual, page 56.
