SimpleNotation
open class SimpleNotation : Notation
A class that defines the simple notation style to be used when formatting numbers in NumberFormatter.
This class exposes no public functionality. To create a SimpleNotation, use one of the factory methods in Notation.

From class Notation
CompactNotation! |
compactLong()
Print the number using long-form compact notation. For more information on compact notation, see compactShort.
In long form, the powers of ten are spelled out fully. Example outputs in en-US when printing 8.765E7 through 8.765E0:
88 million
8.8 million
876 thousand
88 thousand
8.8 thousand
876
88
8.8

CompactNotation! |
compactShort()
Print the number using short-form compact notation.
Compact notation, defined in Unicode Technical Standard #35 Part 3 Section 2.4.1, prints numbers with localized prefixes or suffixes corresponding to different powers of ten. Compact notation is similar to engineering notation in how it scales numbers.
Compact notation is ideal for displaying large numbers (over ~1000) to humans while at the same time minimizing screen real estate.
In short form, the powers of ten are abbreviated. In en-US, the abbreviations are "K" for thousands, "M" for millions, "B" for billions, and "T" for trillions. Example outputs in en-US when printing 8.765E7 through 8.765E0:
88M
8.8M
876K
88K
8.8K
876
88
8.8
When compact notation is specified without an explicit rounding strategy, numbers are rounded off to the closest integer after scaling the number by the corresponding power of 10, but with a digit shown after the decimal separator if there is only one digit before the decimal separator. The default compact notation rounding strategy is equivalent to:
Rounder.integer().withMinDigits(2)

ScientificNotation! |
engineering()
Print the number using engineering notation, a variant of scientific notation in which the exponent must be divisible by 3.
Example outputs in en-US when printing 8.765E4 through 8.765E-3:
87.65E3
8.765E3
876.5E0
87.65E0
8.765E0
876.5E-3
87.65E-3
8.765E-3
0E0

ScientificNotation! |
scientific()
Print the number using scientific notation (also known as scientific form, standard index form, or standard form in the UK). The format for scientific notation varies by locale; for example, many Western locales display the number in the form "#E0", where the number is displayed with one digit before the decimal separator, zero or more digits after the decimal separator, and the corresponding power of 10 displayed after the "E".
Example outputs in en-US when printing 8.765E4 through 8.765E-3:
8.765E4
8.765E3
8.765E2
8.765E1
8.765E0
8.765E-1
8.765E-2
8.765E-3
0E0

SimpleNotation! |
simple()
Print the number using simple notation without any scaling by powers of ten. This is the default behavior.
Since this is the default behavior, this method needs to be called only when it is necessary to override a previous setting.
Example outputs in en-US when printing 8.765E7 through 8.765E0:
87,650,000
8,765,000
876,500
87,650
8,765
876.5
87.65
8.765
