Golang math.Dim() function returns the “maximum of x-y or 0.”
Syntax
func Dim(x, y float64) float64
Parameters
x, y: The values to get the maximum of x-y or 0.
Return value
The Dim() function returns a single value of type float64. This value represents the difference between the two arguments (x-y) and 0.
- Dim(+Inf, +Inf) = NaN: If both parameters are positive infinity, the function returns the Inf.
- Dim(-Inf, -Inf) = NaN: If both parameters are negative infinity, the function returns the Inf.
- Dim(x, NaN) = Dim(NaN, x) = NaN: If any of the parameters is NaN (Not-A-Number), the function returns the NaN.
Example 1: How to Use math.Dim() function
package main
import (
"fmt"
"math"
)
func main() {
fmt.Println(math.Dim(5, 3))
fmt.Println(math.Dim(3, 5))
fmt.Println(math.Dim(5, 5))
fmt.Println(math.Dim(5, math.NaN()))
}Output
2
0
0
NaNExample 2: Calculate the Remaining Space
package main
import (
"fmt"
"math"
)
func main() {
shelfLength := 10.0
boxLength := 6.5
remainingSpace := math.Dim(shelfLength, boxLength)
fmt.Printf("After placing a box of length %.2f on a shelf of length %.2f, the remaining space is %.2f units.\n",
boxLength, shelfLength, remainingSpace)
}
Output
After placing a box of length 6.50 on a shelf of length 10.00, the remaining space is 3.50 units.Example 3: Calculate the Elevation Difference
package main
import (
"fmt"
"math"
)
func main() {
mountainA := 4500.0
mountainB := 4200.0
elevationDifference := math.Dim(mountainA, mountainB)
fmt.Printf("The elevation difference between Mountain A and Mountain B is %.2f meters.\n", elevationDifference)
}Output
The elevation difference between Mountain A and Mountain B is 300.00 meters.Example 4: Passing negative arguments
package main
import (
"fmt"
"math"
)
func main() {
data := math.Dim(-19, -21)
fmt.Println(data)
}Output
2Example 5: Passing zero/zero
package main
import (
"fmt"
"math"
)
func main() {
zero := 0.0
output := math.Dim(zero/zero, 3)
fmt.Println(output)
}Output
NaNThat’s it!
