BigDecimal是标准的类，在编译器中不需要特殊支持，它可以表示任意精度的小数，并对它们进行计算。
BigDecimal is a standard class, with no special support in the compiler, to represent arbitrary-precision decimal Numbers and perform arithmetic on them.
它在各种各样的计算机系统上运行，尤其擅长于涉及任意长度整数和小数、图、矩阵和多项式代数的算术。
It runs on a variety of computer systems and is especially good at arithmetic involving arbitrary-length integers and fractions, graphics, and matrix and polynomial algebra.
在内部，可以用任意精度任何范围的值和一个换算因子来表示BigDecimal，换算因子表示左移小数点多少位，从而得到所期望范围内的值。
Internally, BigDecimal is represented as an arbitrary-precision unscaled value and a scale factor, which represents how many places to move the decimal point left to obtain the scaled value.
该分频器系统能够任意实现包括16位数据输入的小数或整数范围的分频状态，当工作在低频范围时将非常接近理想值。
This system can achieve the 16 bit digital input at its option and the output signal approaches the ideal one when it work at the low frequency.
