数字型(Number) 数字型数据类型包括整型(int)、浮点型(float)、布尔型(bool)和复数型(complex)等。其中,整型用于表示整数,浮点型用于表示浮点数或科学计算中的实数,布尔型用于表示 True 和 False 两个值,复数型用于表示实部和虚部都为浮点数的复数。
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 ...
For example, programmers may need to perform mathematical operations like addition and subtraction between values of different number types such as integer and float. We can use the following built-in functions to convert one number type into another: int(x), to convert x into an integer value...
