Methods for comparing sizes: 1. Use the "compareTo()" method; 2. Use the "equals()" method; 3. Use the overloaded version of the "compareTo()" method; 4. Use the chain of the "compareTo()" method formula calls, etc.
How to compare BigDecimal values in java1. Using the equals() method not only requires that the values of the two BigDecimals are equal, but also requires their scale() to be equal. BigDecimald1=newBigDecimal("123.45");BigDecimald2=newBigDecimal("123.45000");System.out.println(d1.equals(d2));//false, because the scale is different System.out.println(d1.equals(d2) .stripTrailingZeros(
How to use BigDecimal in java1. BigDecimal uses scale() to represent the number of decimal places. BigDecimald1=newBigDecimal("987.65");BigDecimald2=newBigDecimal("987.6500");BigDecimald3=newBigDecimal("98765400");System.out.println(d1.scale());//2, represents two decimal places System. out.println(d2.scale());//4Sy
What is the role of BigDecimal in java1. Explain that the API class BigDecimal provided by Java in the java.math package is used to accurately calculate more than 16 significant digits. Double-precision floating-point variables can handle 16-bit significands, but in practical applications, larger or smaller numbers may need to be calculated and processed. 2. Instance BigDecimala=newBigDecimal(0.1);System.out.println("avaluesis:"+a);System.out.println("==================== ===");BigDecimalb=
