Primitive types

Forms that compile (5)

Syntax	Description
sbyte byte short ushort int uint long ulong	Integer types
float a = 1.5f; double b = 2.5;	float and double
decimal a = 1.5m;	decimal
char c = 'a'; bool b = true;	Characters and booleans
object o = "a"; string s = "b";	object and string

Forms that don’t compile (1)

Syntax	Description	Error	Reason	Instead
System.IntPtr p = System.IntPtr.Zero;	A raw pointer-width integer	TUKI0102, TUKI0099	runtime	Use int or long
Some types aren’t available because the runtime doesn’t have them (TUKI0102). The language itself doesn’t forbid them.

Integers

Integer types

All 8 integer types are available. Integers narrower than int are promoted to int before an operation (Expressions).

using UnityEngine;
using Tsukimi;

public class TyPrimInts : TsukimiBehaviour
{
    void Start()
    {
        sbyte a = 1; byte b = 2; short c = 3; ushort d = 4;
        int e = 5; uint f = 6; long g = 7; ulong h = 8;
        Debug.Log(a + b + c + d + e + (int)f + (int)g + (int)h);   // => 36
    }
}

Fractional numbers

float and double

using UnityEngine;
using Tsukimi;

public class TyPrimFloat : TsukimiBehaviour
{
    void Start()
    {
        float a = 1.5f;
        double b = 2.5;
        Debug.Log(a + (float)b);   // => 4
    }
}

decimal

You can write a decimal literal and convert it to double.

using UnityEngine;
using Tsukimi;

public class TyPrimDecimal : TsukimiBehaviour
{
    void Start()
    {
        decimal a = 1.5m;
        Debug.Log((double)a);   // => 1.5
    }
}

Other

Characters and booleans

char and bool are also carried by value.

using UnityEngine;
using Tsukimi;

public class TyPrimCharBool : TsukimiBehaviour
{
    void Start()
    {
        char c = 'a';
        bool b = true;
        int code = c;
        Debug.Log(code);   // => 97
        Debug.Log(b);   // => true
    }
}

object and string

object and string are carried by reference.

using UnityEngine;
using Tsukimi;

public class TyPrimObjStr : TsukimiBehaviour
{
    void Start()
    {
        object o = "a";
        string s = "b";
        Debug.Log(o.ToString() + s);   // => "ab"
    }
}
