Boolean and integers

Boolean

Booleans have two possible values: True or False.

global C = True;

if (C)
    print "always runs";

Integers

Spicy supports both signed and unsigned integers with widths of 8, 16, 32 and 64 bits:

• uint8, uint16, uint32, uint64
• int8, int16, int32, int64

Integers are checked at both compile and runtime against overflows. They are either statically rejected or trigger runtime exceptions.

Integer literals without sign like e.g., 4711 default to uint64; if a sign is given int64 is used, e.g., -47, +12.

If permitted integer types convert into each other when required; for cases where this is not automatically possible one can explicitly cast integers to each other:

global a: uint8 = 0;
global b: uint64 = 1;

# Modify default: uint8 + uint64 -> uint64.
global c: uint8 = a + cast<uint8>(b);
