Multiplication Operator in Go
Golang Multiplication Operator takes two operands and returns the product of these two operands. Both the operands provided to Multiplication Operator should be of same datatype.
Golang Multiplication Operator applies to integers, floats, and complex values.
Multiplication Operator is also called Product Operator.
In this tutorial, we will learn about the syntax of Multiplication Operator, and some example scenarios on how to use Addition operator.
Syntax
The syntax to multiply two operands a and b, using Multiplication Operator is
a*b
where a and b are operands and * is the operator symbol.
Return Value
The return value is of same datatype as that of first operand.
Examples
Multiply Integers
In the following example, we take two integer values and find their product using Multiplication Operator.
Example.go
package main
func main() {
a := 7
b := 3
result := a * b
println("Multiplication (a*b) = ", result)
} Output
Multiplication (a*b) = 21
Multiply Floating Point Values
In the following example, we take two floating point numbers and find their product using Multiplication Operator.
Example.go
package main
func main() {
a := 4.1
b := 2.2
result := a * b
println("Multiplication (a*b) = ", result)
} Output
Multiplication (a*b) = +9.020000e+000
Multiply Complex Numbers
In the following example, we take two complex numbers and compute their product.
Example.go
package main
func main() {
a := complex(2, 3)
b := complex(5, 1)
result := a * b
println("Multiplication (a*b) = ", result)
} Output
Multiplication (a*b) = (+7.000000e+000+1.700000e+001i)
Multiply Float and Integer
In the following example, we take float value in first operand and integer value in second operand. We try to compute their product using Multiplication Operator.
Example.go
package main
func main() {
a := 3.14
b := 2
result := a * b
println("Multiplication (a*b) = ", result)
} Output
./example.go:6:14: invalid operation: a * b (mismatched types float64 and int)
Conclusion
In this Golang Tutorial, we learned about Multiplication Operator in Go language, with the syntax and example programs.
