Two . #numbers

Handle the conversion of digital data

• Make up for numbers that are not enough 0(formatInteger)
• Set thousands separator (formatInteger)
• Exact decimal point (formatDecimal)
• Set the percent sign (formatPercent)
• Generating arrays (sequence)

#numbers.formatInteger

• Make up for numbers that are not enough 0

<p th:text="${#numbers.formatInteger('123',4)}"></p>  // 0123
<p th:text="${#numbers.formatInteger('123',2)}"></p>  // 123

• Set thousands separator .

<p th:text="${#numbers.formatInteger('1000',2,'POINT')}"></p>  // 1.000
<p th:text="${#numbers.formatInteger('1000',6,'POINT')}"></p>  // 001.000
<p th:text="${#numbers.formatInteger('1000',7,'POINT')}"></p>  // 0.001.000

Set thousands separator ,

<p th:text="${#numbers.formatInteger('1000', 2, 'COMMA')}"></p>  // 1,000
<div th:text="*{#numbers.formatInteger('1000', 0, 'COMMA')}"></div>  // 1,000

Set the thousand separator to blank

<p th:text="${#numbers.formatInteger('1000', 2, 'WHITESPACE')}"></p>  // 1 000
