A round-to-nearest operation takes an original number with an implicit or specified precision; examines the next digit, which is at that precision plus one; and returns the nearest number with the same precision
This function rounds elements of an array to thenearest valuewith the given number of decimals. If you don’t specify the decimals parameter, it rounds to the nearest integer. ReadCopy a NumPy Array to the Clipboard through Python Advanced Rounding Options in NumPy NumPy offers several variatio...
The documentation for the built-inround()function says that it rounds to the nearest value, rounding ties away from zero. Since the decimal fraction 2.675 is exactly halfway between 2.67 and 2.68, you might expect the result here to be (a binary approximation to) 2.68. It’s not, because...

round函数在Python中有很多实际应用场景,尤其是在需要进行数值四舍五入或格式化输出的时候,常见的应用场景有: 1、金融计算:在金融领域,经常需要对货币金额进行四舍五入到特定的小数位数,以符合货币单位的精度要求。 2、数据分析和可视化:在数据分析和可视化过程中,经常需要对数据进行预处理,包括四舍五入以减少噪声或...

Example 3: Round to Nearest 10 The round function can be used to round to the next 10 (i.e. 10, 20, 30, 40…). Consider the following numeric value: x10<-77# Create number with two digits We can round this numeric value (i.e. the number 77) to the closest 10 by specifying ...
RoundToNearest算法是一类较朴素的后量化算法,其取整方式使用了Round to nearest,即四舍五入的方式。 当前金箍棒中的RoundToNearest后量化(后面使用RTN来简称)主要针对LLM(大语言模型场景),使用MinMax校正器对线性层(Linear)进行量化。伪量化的网络结构示意如下: 表1:RTN算法规格 规格规格说明 硬件支持 量化阶段运行...
