binary bit test

[horanyee]

Hi,

I need to test each binary bits using following logic equation.

How do I do this?

((var & (1<<bit)) != 0)

For example

If var = 0111 and bit =2 (start from 0), so third bit of var is 1 and shift by two

are equal, this equation will yield TRUE for third bit.

Things I need to accoplish

1. I need to compare every binary bit

2. result should be in corresponing binary bit.

Can someone show me how?

thank you in advance,

Do

Sorry, I put to wrong equation.

Can we try this?

I need to set the bit using following equation

var |= (1<<bit);

In the Numeric >> Data Manipulation palette, there ist he logical shift function to move a bit.  You can also do boolean logic on integers.
