${#numbers.formatInteger(num,3,'POINT')}
${#numbers.arrayFormatInteger(numArray,3,'POINT')}
${#numbers.listFormatInteger(numList,3,'POINT')}
${#numbers.setFormatInteger(numSet,3,'POINT')} 		Set minimum integer digits and thousands separator Available separators: 'POINT', 'COMMA', 'WHITESPACE', 'NONE' or 'DEFAULT' (by locale).

${#numbers.setFormatPercent(numSet)} 		Formatting percentages
${#numbers.formatPercent(num, 3, 2)}
${#numbers.arrayFormatPercent(numArray, 3, 2)}
${#numbers.listFormatPercent(numList, 3, 2)}
${#numbers.setFormatPercent(numSet, 3, 2)} 		Set minimum integer digits and (exact) decimal digits.
${#numbers.sequence(from,to)}
${#numbers.sequence(from,to,step)} 		Sequence from x to y Create a sequence (array) of integer numbers going from x to y

3. Conclusion

In this article, we presented Thymeleaf utility methods for Number objects. Methods can be useful for formatting numbers, currencies or percentages. With this utility, you do not need to prepare variables before putting them on the template but instead, you can format them accordingly to your needs, directly on the template.
