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...
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。

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...
By using the e or E character, you can represent any floating-point number using scientific notation, as you did in the above examples.Floating-Point Numbers RepresentationNow, you can take a more in-depth look at how Python internally represents floating-point numbers. You can readily use ...

It's incorrect to assume that decimal places are being added since I'm not doing so. Even when I input 1.5E10 in standard notation, it works perfectly fine, even with the inclusion of 8 decimal places resulting in the number 15000000000.00000000. ...
