文档关于decimal模块的总解释是Decimal fixed point and floating point arithmetic,我理解的是固定小数点和浮点运算。头加上from decimal import * 即可调用decimal模块中的内容。 1. Decimal类型的优点 Decimal类型是在浮点类型的基础上设计的,但是它在几个地方上要优于floating point: 1)Decimal类型可以非常精确地在...
1. 创建变量时,指名dtype ,如整数可选int64 int64 意思是64位整数(64bit interger), 相当于 long long 占8个字节 -9223372036854775808 ~ 9223372036854775807 a = ([6, 9], dtype=np.int64) 2.Decimal fixed point and floating point arithmetic 3.@专注于矩阵乘法de中缀算子A dedicated infix operator for...
It’s similar to float as it moves the decimal point around to accommodate larger or smaller magnitudes. However, it operates in the decimal system instead of in the binary. Another strategy to increase numerical precision is fixed-point arithmetic, which allocates a specific number of digits ...

Simple Python Fixed-Point Module (SPFPM)spfpm is a pure-Python toolkit for performing binary fixed-point arithmetic, including trigonometric and exponential functions.The package provides:Representations of values with a fixed number of fractional bits Optional constraints on the number of whole-number...
Fixed Point Python Package The fixedpoint package is a fixed point arithmetic library for python, released under theBSD license. Install fixedpoint withpip install fixedpoint. Package documentation can be found atreadthedocs, or build your own local documentation: ...
In such cases, you’re better off using Python’s decimal module, which implements fixed-point arithmetic and lets you specify where to put the decimal point on a given bit-length. For example, you can tell it how many digits you want to preserve:...
