Summary: Today we consider two of Scheme's core data types: Characters and strings.
> (real? 3/4) #t > (rational? 3/4) #t
(real? 3/4) (rational? 3/4) RUN #t #t
(define ex1a (real? 3/4)) (define ex1b (rational? 3/4)) RUN > ex1a #t > ex1b #t
'is-three-forths-real? (real? 3/4) 'is-three-forths-rational? (rational? 3/4) RUN is-three-forths-real? #t is-three-forths-rational? #t
I usually create these pages
on the fly, which means that I rarely
proofread them and they may contain bad grammar and incorrect details.
It also means that I tend to update them regularly (see the history for
more details). Feel free to contact me with any suggestions for changes.
