Do old Calculators count as Classic Computers?

from the I-thought-it-was-programmable department:

Anyone know what the K key does on my Texas Insturments SR-40 (I'ts got an LED
display, it 'gots' to be old!)

I have googled, I found lots of stuff on a signal processor (?) with that
name, and a few pages that show the calculator, and give a date range for
Mfg. but nothing that describes the keyboard.

I tried pressing the K key in several cases

  5 sin = 5 K sin

 543 = 54K3 (K does not end a number )

tis a puzzlement. : ^ )
