# Integer Math Functions
The following math functions operate on `int64` values.
## add
Sum numbers with `add`. Accepts two or more inputs.
```
add 1 2 3
```
## add1
To increment by 1, use `add1`
## sub
To subtract, use `sub`
## div
Perform integer division with `div`
## mod
Modulo with `mod`
## mul
Multiply with `mul`. Accepts two or more inputs.
```
mul 1 2 3
```
## max
Return the largest of a series of integers:
This will return `3`:
```
max 1 2 3
```
## min
Return the smallest of a series of integers.
`min 1 2 3` will return `1`
## floor
Returns the greatest float value less than or equal to input value
`floor 123.9999` will return `123.0`
## ceil
Returns the greatest float value greater than or equal to input value
`ceil 123.001` will return `124.0`
## round
Returns a float value with the remainder rounded to the given number to digits after the decimal point.
`round 123.555555 3` will return `123.556`
## randInt
Returns a random integer value from min (inclusive) to max (exclusive).
```
randInt 12 30
```
The above will produce a random number in the range [12,30].
