The cat command (see Section 6.3.11) can also be used to transform a real number into a string, as can + (see Section 6.3.12).
If cat has a real number as an argument, the result will be a string.
Example.
Input:
Output:
"123" |
Similarly, if you add a real number to an empty string, the result will be a string.
Example.
Input:
Output:
"123" |
