In the example given below, we havedofdoubledata type, which is obtained by dividing twodoublevariablesd1andd2. Similarly, we havef1resulted when twofloatvariablesf1andf2are divided. In the case ofdouble, there is no need to use the suffixdorD, whereas forfloattype data we need to use the...
使用BigDecimal 类型:在 Java 中,可以使用 BigDecimal 类型来处理大型数值,避免浮点数精度问题。 四舍五入:在进行转换之前,可以先将大型 double 类型数值进行四舍五入,以减少精度损失。 使用类型转换:在某些情况下,可以使用类型转换来将 double 类型数值转换为整数类型,例如使用 (int) 或 (long) 进行转换。 使用...
