How do I use binary - Casio FX-115ES Scientific Calculator

Binary semaphore is a semaphore with the integer value ranges over 0 and 1 whereas the counting semaphore's integer value ranges over unrestricted domain. Binary semaphores are easier to implement comparing with the counting semaphore.
Binary semaphore allows only one thread to access the resource at a time. But counting semaphore allows N accesses at a time.
The 2 operations that are defined for binary semaphores are take and release.
The 2 operations that are defined for counting semaphores are wait and signal

To convert from binary to decimal, we have to line up the numbers with the binary columns.

1 1 1 0 0 0
2^5 2^4 2^3 2^2 2^1 2^0
32 16 8 4 2 1

32 + 16 + 8 + 0 + 0+ 0 = 56

Good luck.

I was able to enter 64 binary digits without getting an argument error. with 65 binary digits and higher one gets the error.

change your mode to binary , then enter your decimal no in dec link and then press bin link you can get the binary equivalent
