formatted_num = format(num, '.2f') print("原始数值:", num) print("科学记数法:", num) print("转换为常规小数:", formatted_num) 在这个示例中,我们使用了SymPy库来表示科学记数法。首先,我们导入了symbols和Eq模块。然后,我们定义了一个符号变量num来表示我们要处理的数值。接下来,我们使用format()...

When there are a lot of leading zeros as in your example, the scientific notation might be easier to read. In order to print a specific number of digits after a decimal point, you can specify a format string with print: print 'Number is: %.8f' % (float(a[0]/a[1])) Or you ...
This creates a logarithmic space with 5 elements ranging from 100 to 104, or from 1 to 10000. The output array shows the numbers 1, 10, 100, 1000, and 10000 in scientific notation. Although base 10 is the default value, you can create logarithmic spaces with any base:...
