sint (Safe Integer)

The sint type provides arbitrary precision integers with no size limit, similar to Python's int. Use sint when you need to work with numbers larger than what the regular int type (64-bit signed) can hold.

Declaration

var sint x = 12345
var sint big = 99999999999999999999999999999999

Integer literals that are too large for a 64-bit int are automatically stored as sint values.

Arithmetic

All standard arithmetic operators work with sint:

import console

var sint a = 99999999999999999999
var sint b = 88888888888888888888
console.println((a + b).tostring())
console.println((a * b).tostring())
console.println((a - b).tostring())
console.println((a / b).tostring())
console.println((a % b).tostring())

When a sint is involved in an operation with a regular int, the result is promoted to sint.

Comparisons

Comparison operators (==, !=, <, >, <=, >=) work between sint and int.

var sint big = 99999999999999999999
var int small = 42
console.println((big > small).tostring())  // true

Methods

Method	Return	Description
`tostring()`	string	String representation
`toint()`	int	Convert to int (errors if value too large for 64-bit)
`tofloat()`	float	Convert to float (may lose precision)
`abs()`	sint	Absolute value
`pow(sint exp)`	sint	Raise to a power

Conversion

From int to sint

var int x = 42
var sint big = x.tosint()

From string to sint

var string s = "123456789012345678901234567890"
var sint big = s.tosint()

From sint to int

var sint big = 42.tosint()
var int x = big.toint()  // works if value fits in 64-bit

When to use sint vs int

Use int for most purposes. It is faster because it uses native 64-bit arithmetic. Use sint when:

You need numbers larger than 9,223,372,036,854,775,807 (max int64)
You are doing cryptographic or mathematical computations with large numbers
You want to avoid integer overflow errors entirely

Note that int arithmetic will throw an Error on overflow, which can be caught with try/catch. With sint, overflow is impossible.
