You can simply use str method to convert float to String. Let’s understand with the help of simple example. 1 2 3 4 f=1.23444432 print("Converted f to String:",str(f)) Output: Converted f to String: 1.23444432
we have to call it on the string that’ll be used for joining. In this case, we’re using a string with a space in it. The method receives a list of strings and returns one string with each of the strings joined by the initial string. Let’s check its functionality with...
@EVERYBODY: You don't need to convert a float to a decimal to preserve the precision. The whole point of the repr() function is that the following is guaranteed: float(repr(a_float)) == a_float Python 2.X (X <= 6) repr gives a constant 17 decimal digits of precision, as that ...
class float([x]) Return a floating point number constructed from a number or string x. If the argument is a string, it should contain a decimal number, optionally preceded by a sign, and optionally embedded in whitespace. The optional sign may be '+' or '-'; a '+' sign has no eff...
floating-point hardware, and on most machines are on the order of no more than 1 part in 2**53 per operation. That’s more than adequate for most tasks, but you do need to keep in mind that it’s not decimal arithmetic and that every float operation can suffer a new rounding error...
小数值表示为Decimal类的实例.构造函数取一个整数或字符串作为参数.使用浮点数创建Decimal之前,可以先将浮点数转换为一个字符串,使调用 者能够显式的处理值的位数,倘若使用硬件浮点数表示则无法准确的表述.另外,利用类方法from_float()可以转换为精确的小数表示: ...

Now that you know the basics of how to interpolate values into your strings using f-strings or .format(), you’re ready to learn about formatting. When you call Python’s .format() method, the template string contains replacement fields. A replacement field consists of three components. Here...
_Number = Union[float, Decimal, Fraction] _NumberT = TypeVar('_NumberT', float, Decimal, Fraction) 这种方法是正确的,但有限。它不支持标准库之外的数字类型,而numbers ABCs 在运行时支持这些数字类型——当数字类型被注册为虚拟子类时。当前的趋势是推荐typing模块提供的数字协议,我们在“可运行时检查的...
