带有货币符号的字符串在 Java 中浮动 [英] String with currency sign to float in Java

问题描述

我想将字符串(例如 $2,480.00, $1.22)转换为浮点值(预期结果:2480.00, 1.22).哪种方式最好?通过循环，留下字符串数字和 '.'或者也许使用正则表达式?

i want to convert Strings (for example $2,480.00, $1.22) to float values (expecting results: 2480.00, 1.22). Which way is best to do it? By loop, leaving in string digits and '.' or maybe with regex?

推荐答案

去掉非数字和非点字符后，只需将字符串解析为浮点:

Just parse the string as float after removing non-number and non-dot characters:

float money = Float.parseFloat("$2,480.00".replaceAll("[^\\d.]", ""));
