Integer Types on the HP Prime
On the HP Prime, the integer type is used for Boolean function calculations. Symbolize integer types by preceding it by a hashtag # and designated a letter at the end of the integer: b for binary, o for octal, d for decimal, and h for hexadecimal.
Example: #11010b represents the binary number 11010.
You can specify the bit size, from 1 to 64, by attaching a colon and bit size in between the integer and it's indicator.
Example: #11010:8b represents the 11010 in an 8-bit format. You can specify the default size in the Home Settings.
NAND (Not And)
The function NAND is also known as the Shaffer function.
nand(A, B) = not(A and B)
nand(1100 1010, 1110 0011) = not(1100 1010 and 1110 0011) = 0011 1101
NOR (Not Or)
The function NOR is also known as the Peirce function.
nor(A, B) = not(A or B)
nor(1100 1010, 1110 0011) = not(1100 1010 or 1110 0011) = 0001 0100
Equivalence (←→), XNOR
A ←→ B = (not A and not B) or (A and B)
1100 1010 ←→ 1110 0011
= 1100 1010 xnor 1110 0011
= (not 1100 1010 and not 1110 0011) or (1100 1010 and 1110 0011)
= 1101 0110
Implication (→)
A → B = (not A) or B
1100 1010 → 1110 0011
= (not 1100 1010) or 1110 0011
= 1111 0111
