Comparison operator performance (>, >=, <, <=)

If you were to compare two integers, would the operator have an impact on the time required to perform the comparison? For example, given:

if (x < 60)

and

if (x <= 59)

Which would provide the best performance, or would the performance difference be negligible? Are the performance results language-dependent?

I often find myself mixing the use of these operators within my code. Any thoughts would be appreciated.

Solution

  • Even if there was noticeable difference, I think compilers are smart enough to care for such things. So my advice is to use what makes the code easier to understand, and leave micro-optimizations to the compiler.
