What is the numpy.reciprocal() function in NumPy?

Overview

The numpy.reciprocal() function in NumPy is used to compute the reciprocal of an argument x , which has been passed to it.

The reciprocal of a number is the value obtained when 1 is divided by that number.

Mathematically, this is represented as follows:

numpy.reciprocal(x) = $\frac{1}{x}$

Syntax

Parameter values

The numpy.reciprocal() function takes the following parameter values.

• x: This represents input array and is a required parameter.
• out: This represents the location where the result is stored and is an optional parameter. 
• where: This is the condition over which the input is being broadcast. The resulting array will be set to the ufunc result at a given location where this condition is True. Otherwise, the resulting array will retain its original value. This is an optional parameter.
• **kwargs: This represents other keyword arguments and is an optional parameter.

Example

Explanation

• Line 1: We import the numpy module.
• Line 4: We create an array x using the array() method.
• Line 7: We implement the np.reciprocal() function on the array. The result is assigned to a variable, myarray.
• Line 9: We print the myarray variable.
