Raku kurss / Pamati / Skaitļi / Veselie skaitļi

Tests: Unikode cipari un skaitļi

Try to find out which of the following digits form integers that Raku accepts as the Int type values.

1	3
1	12345
1	⓷	This is considered a number, not a single digit.
0	⓵⓶⓷⓸⓹	So you cannot combine them in such a way to get `12345`.
1	❷
0	❸❹❺
1	㊷	A single Unicode character named `CIRCLED NUMBER FOURTY TWO`.
0	⓸⓶	But the two numbers are not a number.
1	㊄	Circled Chinese 5 and it is a number `CIRCLED IDEOGRAPH FIVE`.
0	五	While this means 5, the character is neither a digit nor a number.
0	一二三四五

Comments

You can take the following program as a starting point to play with and explore the properties of such digits. Uncomment the lines to see if that compiles.

my $x;
$x =  3;
say $x; say $x.WHAT;

$x =  12345;
$x =  ⓷;
# $x =  ⓵⓶⓷⓸⓹;

$x =  ❷;
# $x =  ❸❹❺;

$x =  ⒌;
# $x =  ⒊⒋⒌;

# $x =  ㊀㊁㊂㊃㊄;
$x =  ㊄;
say $x; say $x.WHAT;

# $x =  五;
# $x =  一二三四五;

$x = ㊷;
say $x;
