After all these conversions, we lose precision due to two factors: We lose precision when converting from the infinite binary representation (which has repeating values like 1100110011). We lose precision when converting to IEEE format because we consider only the first 32 or 64 bits. This means...
Floating-Point Types, Formats, and Values The floating-point types arefloatanddouble, which areconceptually概念associated with thesingle-precision 32-bitanddouble-precision 64-bitformat IEEE 754 values and operations asspecified指定 inIEEE Standard for Binary Floating-Point Arithmetic, ANSI/IEEE Standard ...
Note that while decimals can accurately represent non-repeating decimal fractions, their precision isn't any better than that of floating-point numbers; choosing decimals merely means you get exact representations of numbers that can be represented exactly in a decimal system (just like floats can...

在Java中,浮点运算指的是对浮点数进行加减乘除等基本运算操作。Java 提供了两种浮点类型:float 和 double。 2. 为什么 Java 浮点运算不精确? Java 浮点运算不精确主要是由于浮点数的内部表示方式以及计算机硬件的限制所导致的。 2.1 浮点数的内部表示 浮点数在计算机中采用二进制科学计数法来表示,即将一个实数分解为...
