In PHP, bccomp() function is used to compare two arbitrary numbers. The bccomp() function takes two arbitrary precision numbers as strings and gives the output as an integer after comparing the two numbers.Syntaxint bccomp($left_string1, $right_string1, $scaleval)ParametersThe bccomp() function accepts three different parameters− $left_string1, $right_string2 and $scaleval.$left_string1− It represents the left operand of one of two given numbers which we want to do the comparison and it is a string type parameter.$right_string2− It represents the right operand of one of two given numbers which we want to do the comparison and it is a string type parameter.$scaleval− It returns the number ...

In PHP, bcdiv() math function is used to divide one arbitrary precision number from another number. The bcdiv() function takes two arbitrary precision numbers as strings and it gives the result as a division of two numbers after scaling the result to an identified precision. Or, we can say that the bcdiv() PHP function divides the dividend by the divisor.Syntaxstring bcdiv($num_string1, $num_string2, $scaleVal)ParametersThe bcmul() math function accepts three different parameters $num_string1, $num_string2 and $scaleVal.$num_string1 − It represents the dividend and it is the string type parameter.$num_string2 − It represents the divisor, it is the string type parameter.$scaleVal − It is the optional ...

In PHP, bcmod() math function is used to calculate the modulus of an arbitrary precision number. The bcmod() function takes an arbitrary precision number as strings and it gives the result as a modulus of numbers after scaling the result to an identified precision. Or, we can say that it gets the remainder after dividing string_num1 by string_num2. Unless the string_num2 is 0, the result has the same sign as string_num1.Syntaxbcmod(string_$num1, string_$num2, [, int $scale=0])Or, bcmod(string $dividend, string $divisor[, int $scale=0])Note− The above syntax will get the remainder of dividing $string_num1 by $string_num2. Unless string_num2 is 0, the result has ... Read More
In PHP, bcmul() math function is used to multiply one arbitrary precision number with another number. The bcmul() function takes two arbitrary precision numbers as strings and it gives the result as the multiplication of two numbers after scaling the result to an identified precision.Syntaxstring bcmul( $num_string1, $num_string2, $scaleVal)ParametersThe bcmul() math function accepts three different parameters $num_string1, $num_string2 and $scaleVal.$num_string1 - It represents the left operand and it is the string type parameter.$num_string2 - It represents the right operand, it is the string type parameter.$scaleVal - This is the optional integer type parameter that is used to set the number of digits ...

In PHP, bcpow() function is used to raise an arbitrary precision base number to another exponent number. It takes two arbitrary precision numbers as strings and gives the base number raised to the power exponent after scaling the result to the listed precision.SyntaxString bcpow($base, $exponent, $scale)ParametersThe bcpow() function in PHP takes three different parameters: $base, $exponent and $scale.$base - It represents the base in which power will be raised and it is the string type parameter.$exponent - It represents the exponent and it is the string type parameter.$scale - It indicates the number of digits that appear after the decimal in ...

In PHP, bcadd() math function is used to add two arbitrary precision numbers. The bcadd() function takes two random precision numbers as strings and it returns the addition of the two numbers after scaling the result to an identified precision.Syntaxstring bcadd ( $num_str1, $num_str2, $scaleVal)ParametersThe bcadd() math function accepts three different parameters, $num_str1, $num_str2 and $scaleVal.$num_str1 - It represents the left operand and it is the string type parameter.$num_str2 - It represents the right operand and it is the string type parameter.$scaleVal - It is the optional parameter that is used to set the number of digits after the decimal place in the ...

An Entry widget is a basic one-line character widget that supports only single-line text input. An Entry widget can be defined by initializing the Entry(parent, width) constructor.To validate the Entry widget, we can use the get() method which results in the character entered in the Entry widget.Let us define an Entry widget that accepts single-line text input, and we will print the character that is input in the Entry widget.Example#Import the required Libraries from tkinter import * from tkinter import ttk #Create an instance of Tkinter frame win = Tk() #Set the geometry of Tkinter frame win.geometry("750x250") def get_content(): ...

We often use Open and Save Dialog. They are common across many applications and we already know how these dialogs work and behave. For instance, if we click on open, it will open a dialog to traverse the location of the file. Similarly, we have the Save Dialog.We can create these dialogs using Python tkFileDialog package. In order to work with the package, we have to import this in our environment.Type the following command to import the tkFileDialog package in the notebook, from tkinter.filedialog import asksaveasfileExampleIn this example, we will create an application that will save the file using the ...

Testing in a White BoxWhite Box Testing is a software examining technique that involves testing the product's underlying structure, design, and coding in order to verify input-output flow and improve design, usability, and security. White box testing is also known as Clear box testing, Open box testing, transparent box testing, Code-based testing, and Glass box testing since the code is visible to the testers.It's one of two components of the software testing approach known as Box Testing. Blackbox testing, on the other hand, entails testing from an external or end-user perspective. White box testing, on the other hand, is focused ... Read More
Thread testing is client-server-based testing to verify the primary function of an application. It is used to determine whether the application can run a specific task or thread or not.Why Thread Testing is important?Software is split into several threads with each thread running a specific task. When all components of the software are integrated, it is time for the developer to ensure the program runs as expected. For example, if it is a banking app, then the developer must make sure the app can execute all the transactions as per the client’s requirement. This is where thread testing comes to ... Read More
