If I create variable with the *int32_t* type with the value of 1 for example and another variable with the same type but the value will be the *int32* max value, will computations be faster in expressions with the first variable rather than the second?

### >Solution :

In the comments, you asked

So, theoretically the bigger value variable could be faster than the smaller one depending on computations?

which generalizes the question to

- Could computation time differ between inputs with value
`1`

and inputs with value`MAX_INT`

?

For many elementary operations such as addition and bit-wise OR, the answer is *No*.

For arbitrary computation, the answer is *Most definitely yes, unless you are very careful to prevent it*.

The possibility of correlation between input values and time is quite significant in the information security community. Good search terms: "**timing side channel**" and "constant-time implementation".

A related concern is whether the power consumption of the arithmetic circuitry correlates to input values, even when the time is constant.
