同样是保留了两位小数,使用quantize函数能完成同样的效果,默认结果也是经过了四舍五入的计算,若是想要固定小数位数使用此方法比较靠谱。 # It imports all the names from the decimal module into the current namespace.fromdecimalimport*# Rounding the number 3.7829 to two decimal places.decimal_ = Decimal('...
Learn how to round a number to 2 decimal places in Python for improved precision using techniques like round(), format(), and string formatting techniques.
In Python, we can represent decimal values using the float datatype. The decimal point divides the integer from the fractional part. The maximum value a float object can have is 1.8 x 10^308.In this article, we will discuss how to count the decimal places in Python. We will take a ...
