Modifier and Type  Method and Description 

static CompactNotation 
compactLong()
Print the number using longform compact notation.

static CompactNotation 
compactShort()
Print the number using shortform compact notation.

static ScientificNotation 
engineering()
Print the number using engineering notation, a variant of scientific notation in which the
exponent must be divisible by 3.

static ScientificNotation 
scientific()
Print the number using scientific notation (also known as scientific form, standard index form, or
standard form in the UK).

static SimpleNotation 
simple()
Print the number using simple notation without any scaling by powers of ten.

public static ScientificNotation scientific()

public static CompactNotation compactShort()
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 enUS, the abbreviations are "K" for thousands, "M" for millions, "B" for billions, and "T" for trillions. Example outputs in enUS 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)

In long form, the powers of ten are spelled out fully. Example outputs in enUS when printing 8.765E7 through 8.765E0:
88 million 8.8 million 876 thousand 88 thousand 8.8 thousand 876 88 8.8

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 enUS 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
