- \ Lesson 3 Part 4 ( F-PC 3.5 Tutorial by Jack Brown )
-
- COMMENT:
- In part 3 of lesson 4 we introduced the words DECIMAL OCTAL and HEX for
- switching the radix of Forth's number system to 10, 8 and 16
- respectively. These words are included as part of the F-PC system.
- However F-PC does not include a word to set the radix to 2 so that we
- can study binary or base 2 numbers. We can easily make a word called
- BINARY that will switch the radix to 2.
