# Mod()

The `Mod()` function returns the floating-point remainder of dividing x by y. The result has the same sign as x and a magnitude less than the magnitude of y.

The `Mod()` function operates exclusively with floating-point numbers.

Note: If the numbers involved in the operation are of integer type, the `%` modulus operator should be used instead. The `%` operator works with integers, while `math.Mod()` operates with floating-point numbers.

## Syntax

``````math.Mod(x,y)
``````

The `Mod()` function takes two arguments of type ‘float64’.

Please be aware of the following special cases:

1. If the argument has a `+Inf` value, the return value will be `0`:
2. If the value of `x` is either `(±)Inf` or `NAN`, the return value will be `NaN`.
3. The return value is `NAN` if the value of the second argument is either `0` or `NAN`.
4. If `(±)Inf` is passed as the second argument, the return value is `x (first argument)`.

## Example

The following example demonstrates how to use the `Mod()` function and print the result:

```package main
import(  "fmt"  "math")
func main() {  a:= 23.50  b:= 5.20
modResult := math.Mod(a, b)  fmt.Printf("The modulus of %.2f and %.2f = %.2f", a, b, modResult)}
```

The output will be:

```The modulus of 23.50 and 5.20 = 2.70
```
