Arduino char math code#

The arithmetic operators used in Arduino are + for addition, – for subtraction, * for multiplication, / for division, and % for remainder. In conclusion, Arduino IDE is capable of performing basic arithmetic operations such as addition, subtraction, multiplication, division, and remainder.

Serial Monitor Response: Remainder of Num1 and Num2 is 1 Serial.print('Remainder of Num1 and Num2 is ') It is represented by the percentage sign (%). The remainder operator calculates the remainder after one number is divided by another number. When using constant values in calculations that store the result in a floating point variable, use a decimal point and a zero for whole numbers, e.g. Serial Monitor Response: Division of Num1 and Num2 is 1.20 However, if we use float as the data type of the variable to store the result, we get the correct result. The result will be 1 because the numbers after the decimal point are discarded when the result is stored in the variable because its data type is int. Serial Monitor Response: Division of Num1 and Num2 is 1 But what if the result is a floating-point number (numbers with a decimal) and not an integer? Let’s find out with the help of the example given below: int Num1 = 6 Till now we have used division only for integers and have got an integer as a result. There is, however, one more thing you should know about division. Serial Monitor Response: Division of Num1 and Num2 is 5 Serial.print('Division of Num1 and Num2 is ') Given below is an example: int Num1 = 15 It is represented by the division sign (/). The division operator divides one number by another. Serial Monitor Response: Multiplication of Num1 and Num2 is 15 Serial.print('Multiplication of Num1 and Num2 is ') The multiplication operator multiplies one number with another. Serial Monitor Response: Subtraction of Num1 and Num2 is 12 Serial.print('Subtraction of Num1 and Num2 is ') The subtraction operator subtracts one number from another. After statement 5 is executed, the Sum will have a value of 18. This variable is used to store the sum of Num1 and Num2 this value will overwrite the random value when you assign it to Sum. Sum is defined and no value is assigned to it hence, it contains a random number. A value is assigned to both of them as well.

In the code above, two variables are defined, namely Num1 and Num2.

Serial Monitor Response: Addition of Num1 and Num2 is 18 Serial.print('Addition of Num1 and Num2 is ') The addition operator is used for adding two numbers. Arduino has the following five arithmetic operators for basic mathematical operations: Arduino IDE is capable of doing basic arithmetic operations.
