math.trunc

Python math.trunc()方法 (Python math.trunc() method)

math.trunc() method is a library method of math module, it is used to get the truncated integer value of a number, it accepts a number (either an integer or a float) and returns the real value truncated to an integral.

math.trunc()方法是math模塊的庫方法，用于獲取數(shù)字的截斷整數(shù)值，它接受數(shù)字(整數(shù)或浮點數(shù))并返回被截斷為整數(shù)的實數(shù)值。

Note: If anything is passed except the number, the method returns a type error, if we pass a string – it will return "TypeError: type str doesn't define __trunc__ method"

注意：如果傳遞了除數(shù)字以外的任何內(nèi)容，則該方法將返回類型錯誤，如果我們傳遞一個字符串，則將返回“ TypeError：類型str未定義__trunc__方法”

Syntax of math.trunc() method:

math.trunc()方法的語法：

math.trunc(n)

Parameter(s): n – an integer or a float number.

參數(shù)： n-整數(shù)或浮點數(shù)。

Return value: int – it returns an integer value that is the integral part of the number n.

返回值： int –它返回整數(shù)值，該整數(shù)值是數(shù)字n的整數(shù)部分。

Example:

例：

Input:a = 10.23# function callprint(math.trunc(a))Output:10

Python代碼演示math.trunc()方法的示例 (Python code to demonstrate example of math.trunc() method)

# Python code demonstrate example of # math.trunc() method# importing math module import math# numbers a = 10 b = 10.23 c = -10 d = -10.67 e = 10.67# printing the fractional and integer part # of the numbers by using math.trunc()print("trunc(a): ", math.trunc(a)) print("trunc(b): ", math.trunc(b)) print("trunc(c): ", math.trunc(c)) print("trunc(d): ", math.trunc(d)) print("trunc(e): ", math.trunc(e))

Output

輸出量

trunc(a): 10 trunc(b): 10 trunc(c): -10 trunc(d): -10 trunc(e): 10
