Chinese numerals (the characters for one, two, three and so on) are not decimal digits and stay unchanged.

“只保留数字与符号”会合并数字吗？Does Digits and signs only merge numbers?

不会。数字中的千位逗号（1,234）会去掉，其他字符都换成一个空格，所以“½ ¼”得到 1/2 1/4，“$1,234.50 ＋５％”得到 1234.50 +5；不含数字的片段（如货币符号）会被丢弃。科学计数法保持完整（1e5、2e-3），阿拉伯小数点 ٫ 会变成点。No. Thousands commas inside numbers (1,234) are removed and every other character becomes a single space, so ½ ¼ gives 1/2 1/4 and $1,234.50 ＋５％ gives 1234.50 +5; pieces without digits, such as currency signs, are dropped. Scientific notation stays together (1e5, 2e-3), and the Arabic decimal separator ٫ becomes a dot.
