In Java, A BigDecimal "bug" that causes double Precision loss, bigdecimaldouble Background In the blog's disgusting 0.5 rounding question, I saw a question about 0.5 incorrect rounding. It is mainly said that after double is converted to BigDecimal,

In math. when performing data processing, round often encounters a situation where 81.25 retains a decimal number, and the value is 81.2. It is searched by material and math. the round rounding algorithm adopts the banker's rounding algorithm, which

double and float are floating point types. Doubles (double type) are more accurate than float (single-precision) data and occupy more space. Double precision is twice times that of float, so a double is often used for more precise calculations.
