Struct Settings 

pub struct Settings {
    pub format: NumberFormat,
    pub comma: bool,
    pub base: Base,
    pub word_size: u32,
    pub all_parens: bool,
    pub real_point: bool,
    pub power_right: bool,
    pub group_digits: bool,
    pub tag_colon: bool,
}

The display settings the text depends on.

Fields

format: NumberFormat

Real number format.

comma: bool

Comma as the fraction mark (flag -51); the separator in complex numbers becomes ;.

base: Base

Binary integer base (flags -11, -12).

word_size: u32

Binary integer word size in bits, 1-64 (flags -5 to -10).

all_parens: bool

Show every parenthesis in algebraics (flag -53).

real_point: bool

Reals with an integer value keep their point (5.), as on the 49G, whose exact integers show without one (not inside unit objects).

power_right: bool

^ groups to the right (A^B^C is A^(B^C)), as on the 49G; on the 48 it groups to the left.

group_digits: bool

FIX groups the integer digits by three (1,234.500; 1.234,500 with a comma fraction mark) inside lists, programs, arrays and tagged objects too, as the 49G does; both models group a real that is a whole stack level. Never inside complex numbers, algebraics or units.

tag_colon: bool

A tagged object inside a composite shows its tag between colons (:T: 5, the 48) or with a trailing one only (T: 5, the 49G, and both models for a whole stack level).

Implementations

impl Settings

pub fn standard(model: Model) -> Settings

The defaults of model.

pub fn from_flags(flags: &Flags, model: Model) -> Settings

The settings flags select on model.

pub fn for_editing(self) -> Settings

These settings for text that is edited and compiled again: every digit of a real (STD), binary integers at 64 bits, no digit grouping and tags between colons, so that the text compiles back to the same object; the fraction mark, base and parentheses stay.

pub fn binary(&self, value: u64) -> String

value as a binary integer in the base and word size.

pub fn real(&self, r: &Real) -> String

r as the calculator shows it.

pub fn unit_number(&self, r: &Real) -> String

A unit object’s number or power: an integer value as an integer (2_m^2 even in FIX), anything else in the display mode; never a trailing point or digit groups (oracle-checked: 1.50E0_m^2.50E0 in 2 SCI).

pub fn complex(&self, re: &Real, im: &Real) -> String

A complex number (re,im).

Trait Implementations

impl Clone for Settings

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copy for Settings

impl Debug for Settings

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for Settings

fn default() -> Self

The calculator’s defaults: STD, period, decimal binaries, 64 bits.

impl Eq for Settings

impl PartialEq for Settings

fn eq(&self, other: &Self) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
