Join ()()

Category Operators
Type Reporter

The Join ()() block is an Operators block and a Reporter block. The block 'sticks' the two values together and reports the result - for example, if "hello" and "world" were put in the block, it would report "helloworld".

This block was introduced in Scratch 1.4, along with other string blocks.

Example Uses

If words, numbers, sentences - any two values - must be stuck together, this block easily does the job.

Some common uses for the Join ()() block:

  • Sticking together words and variables to create a sentence

File:Hello (answer).gif

  • Place a variable in a message (eg. "You completed 2 loops")
  • An easy method of making a positive number turn negative (placing "-" in the first input and the positive number in the second)

Offline decimal trick

Offline, numbers in variables and speech bubbles usually round to only two decimal places. In some projects, it is necessary to have more. Placing the calculation in one input of the Join ()() block and leaving the other input empty 'magically' reports the number with more decimal places.

  • The original script:

  • Script with more decimals:

  • To set the number of decimal places, use a script like this:
