JS retains two decimal places JS retains two decimal places For floating point numbers with multiple digits after decimal points, we may only need to retain two digits, but JS does not provide such a direct function. Therefore, we have to write the function to implement this function by ourselves. The Code is as follows: Function changetwodecimal (X){VaR f_x = parsefloat (X );If (isnan (f_x )){Alert ('fun

Mode one:RoundedDouble F = 111231.5585;Rounding to keep two decimal digits, you can use the Format function of string,The method is as follows: Copy Code code as follows: System.out.println (String.Format ("%.2f", X1)); System.out.println (String.Format ("%.2f", x2)); DecimalFormat conversion is the easiest Copy Code code as follows: public void m2 () { DecimalFormat df = new DecimalFormat ("#.00"); System.out.println (Df.format (f)); } Exampl

The number of decimal places in a repeating prime number must be smaller than that in the prime number itself. Generally, decimal places with the reciprocal of prime numbers are complex. Because the reciprocal of prime numbers is also a fraction, it must be a round-robin decimal (except for 2 and 5 ), but what is the maximum number of decimal places in the c

1. functionThe double value in the program is accurate to two digits after the decimal point. Can be rounded or truncated directly.For example: Enter 12345.6789, the output can be 12345.68 or it can be 12345.67. As to whether rounding is required, parameters can be used to determine (Roundingmode.up/roundingmode.down, etc.).2.

representation "123. So what does 0.1 mean? Is the result of 1*10 ^-1, number to the right. The decimal point is used to distinguish the location of a single digit. A number must be represented by a digital representation. It must be in the form of x * 10 ^ k, not any number. From the definition of decimal digits, we can know that to be expressed as a number, a number of x * 10 ^ k digits must be expressed in addition to 10, otherwise, it is represented by countless symbols. For example, the nu
