- (multiplication)
The multiplication operator, * (asterisk character), returns the multiplication of the arguments before and after it.
$MyNumber = 3*4;
Both arguments are normally Number-type data.
Multiplying Strings
Sometimes there is a need to expand or repeat a String. For this, the multiplication operator * may be used. Due to Tinderbox's internal type coercion effects, the number argument must be used as the first argument; placing it after the * will cause a silent fail with no resulting output. Thus, the expression:
$MyString = 3*"xyz ";
evaluates to a string "xyz xyz xyz". But this:
$MyString = "xyz "*3;
will return nothing.
Multiplying Lists and Sets
From v9.1.0, Lists and Sets of numbers may be multiplied by a number. Two lists of numbers may be multiplied if they have the same length, in which case their elements are multiplied.
1;2;34 * 1;2;3;4 ➛ 1;4;9;12
or, using the range operator:
1...4 * 1...4 ➛ 1;4;9;12
