3.3-Working with Binary Arithmetic Operators

Question 1

📝️ What is a binary operator?

Answer 1

A binary operator is an operator that operates on two operands and manipulates them to return a result.

Question 2

📝️ What is the binary operator’s syntax?

Answer 2

operand1 BI-OPERATOR operand2

Question 3

📝️ What are the Arithmetic operators and its precedence?

Answer 3

• > Multiplication Operator *
• > Division Operator /
• > Remainder Operator %
• > Addition Operator +
• > Substraction Operator -

⚠️The multiplicative operators (*, /, %) have a higher order of precedence than the additive ones (+, -)

Question 4

What does the Modulus Operator return?

Answer 4

It returns the remainder when two numbers are divided.

🧠️🤯️⚠️📣️ Be sure to understand the difference between arithmetic division and modulus.

Question 5

📝️ What does the expression floor value means?

Answer 5

• > For integer values, division results in the floor value
• > It just means the value without anything after the decimal point.

👀️ e.g: The floor value is 4 for each of the values 4.0, 4.5, and 4.9999999.

Question 6

🧠️🤯️⚠️📣️ What does Numeric promotion means?

Answer 6

🚀️ When applying an arithmetic operator ( +|-||/|% ) the result type promotes to int by default**
🚀️ If either operand is long|float|double type, the result is converted to long|float|double
