math.radians() method is a library method of math module, it is used to convert angle value from degree to radians, it accepts a number and returns the angle value in radians.
math.radians()方法是数学模块的库方法,用于将角度值从度转换为弧度,它接受一个数字并以弧度返回角度值。
Note: math.radians() method accepts only numbers, if we provide anything else except the number, it returns error TypeError – "TypeError: a float is required".
注意: math.radians()方法仅接受数字,如果我们提供除数字以外的任何其他内容,它将返回错误TypeError – “ TypeError:需要浮点数” 。
Syntax of math.radians() method:
math.radians()方法的语法:
math.radians(x)
Parameter(s): x – is the number in degree to be converted into radians.
参数: x –是要转换为弧度的度数。
Return value: float – it returns a float value that is the angle value in radians.
返回值: float-它返回一个浮点值,即以弧度为单位的角度值。
Example:
例:
Input: x = 10.25 # function call print(math.radians(x)) Output: 0.17889624832941878
# Python code to demonstrate example of # math.radians() method# importing math moduleimport math # number in radiansx = 0print("math.radians(",x,"): ", math.radians(x))x = 0.25print("math.radians(",x,"): ", math.radians(x))x = 10.25print("math.radians(",x,"): ", math.radians(x))x = -0.25print("math.radians(",x,"): ", math.radians(x))
