JS retains 2 decimal places (mandatory) If the number of decimal places is greater than 2 digits, it is okay to use the above function, but if it is smaller than 2 digits, for example: Changetwodecimal (3.1) will return 3.1. If you need a format like 3.10, you need the following f...
indicating optionality should be eliminated while ensuring that the digit character (\d) comprises of 1 to 3 digits. /^[0-9,]+\.\d{1,3}$/ The meaning of this is to match the start of the string (^), then followed by at least one digit or comma character. The plus symbol (+) ...
It looks like your RoundToDecimal() function is the culprit with regards to what is adding your decimal (as it replaces the value with a fixed 2 digit number after parsing it as a float) : 複製 function RoundtoDecimal(ctrl) { if (ctrl.value.length > 0) { var num = parseFloat(c...
2.实现原理 各类语言及数据库一般都提供了DECIMAL 类型的支持,一般是以一个 struct 来表示一个 DECIMAL 类型。 比如MySQL的实现是: 代码语言:javascript 代码运行次数:0 运行 AI代码解释 typedef int32 decimal_digit_t;struct decimal_t{int intg,frac,len;bool sign;decimal_digit_t*buf;}; Golang 库 githu...

Thousands separator Separates the thousands in digit grouping. Commas are most commonly used as thousands separators. Based on the user's locale, other symbols (such as periods) or custom characters can be used as thousands separators. String Decimal separator Separates the integral and the fractiona...
By default this returns the number in standard number format, comma after every three digits. Both arguments,digits- the number of digits (of the integral part) to group by, andseparator- the character to mark the separation. Example of this can be to format a 16 digit number ascredit car...

scale 是小数点后面的 digit , max is 38 , default is 0; precision 不会自动调整的,比如我的 scale = 10, 那么 precision - 10 就等于小数点左边可以放的digit . 所以 decimal(18,18) 就表示只能放 0.xxx... 而不可以是 1.xxxx... select ROUND(50.556,2,0); //result : 50.560 四舍五入 ...
