The round() function truncates the decimal digits down to 2, the format() function sets the precision of the decimal places, the Decimal module quantizes the number to the desired decimal places, and the ceil() function from the math module rounds the decimals up to the nearest integer. ...
num = 3.141592653589793 decimal_places = 3 result = truncate_float(num, decimal_places) print(result) # 输出:3.141 在上述示例中,我们将浮点数3.141592653589793截断为3位小数,得到的结果为3.141。 腾讯云相关产品推荐:若您在云计算领域中需要进行浮点数截断操作,您可以考虑使用腾讯云的云函数(SCF)。云函数...
The truncate() function first shifts the decimal point in the number n three places to the right by multiplying n by 1000. You get the integer part of this new number with int(). Finally, you shift the decimal point three places back to the left by dividing n by 1000....

Truncate Numbers With trunc()When you get a number with a decimal point, you might want to keep only the integer part and eliminate the decimal part. The math module has a function called trunc() which lets you do just that.Dropping the decimal value is a type of rounding. With trunc(...
