下面是一个完整的代码示例,演示了如何使用Python将科学计数法转换为整数: defconvert_scientific_notation(scientific_notation):converted_number=int(scientific_notation)returnconverted_number# 测试示例scientific_notation_1="1e6"converted_number_1=convert_scientific_notation(scientific_notation_1)print(converted_numb...
例如,对于数值1.23456789e+9,我们需要将指数部分9转换为小数点后的位数,即9位。因此,科学记数法1.23456789e+9转换为常规小数表示法即为123456789.0。 同样地,对于数值1.23456789e-9,我们需要将指数部分-9转换为小数点前的位数,即1位。因此,科学记数法1.23456789e-9转换为常规小数表示法即为0.0000000123456789。 科学记...
All floating-point numbers must have a decimal part, which can be 0, which is designed to distinguish floating-point numbers from integer types. There are two kinds of decimal representation and scientific notation. Scientific numeration uses the letter e or E as a symbol for a power, with 1...

The fractional notation is typically associated with rational numbers only. After all, the very definition of a rational number states that you can express it as a quotient, or a fraction, of two integers as long as the denominator is nonzero. However, that’s not the whole story when you...
Note: E notation is short for exponential notation. You may have seen this notation used by calculators to represent numbers that are too big to fit on the screen.To write a float literal in E notation, type a number followed by the letter e and then another number. Python takes the ...
