Types

The sizes are the same on Linux and Windows.

Numbers

a := 1_000_000      // _ is ignored
b := 0xFF
c := 0b1010
d := 0o17
print(a, b, c, d)

1000000 255 10 15

A whole number is an int. A number too big for int becomes an int.long:

small := 7
big := 3000000000
int.long sum := big + small
print(sum)

3000000007

Chars

A char holds one letter, in single quotes. Any Unicode letter works:

a := 'A'
alef := 'א'
newline := '\n'
smile := '\u{1F600}'
print(a, alef, smile)

A א 😀

Conversions

A smaller type turns into a bigger one by itself:

int.short s := 300
int.long l := s
print(l)

300

To go smaller, or between numbers and chars, convert with the type's name. The program checks that the value fits:

x := 300
print(int.short(x), int.long(x) * 2)
print(char(65), int('A'))
print(unsigned int(42), string(7) + "!")

300 600
A 65
42 7!

If the value doesn't fit, the program stops with an error:

error: this value doesn't fit in byte (0 to 255)
  --> main.cfl:2:6

Signed and unsigned numbers of the same size don't mix; convert one side first.

double and float are planned for the next version.
