why is it that in most programming languages the mathematical operators precedence is different from the logical operators precedence.
meaning: why is x / y * z evaluates to ( x / y ) * z so that / has the same precedence as * but in logical operators x || y && z would evaluate to x || ( y && z )
So, is there a logical reason for this distinction ( some hardware reason, optimization technique) or is it just the way programming language creators decided to make them??
It's not about programming. Ever worked with boolean algebra? AND has precedence over OR there too, and boolean algebra is from the 17th century (though I don't know when this convention came to be). The two are also written as * and +, which gives a clue in that regard (but can confuse in others).
Programming language designers just carried these precedence rules over, just like they carried over the precedence of arithmetic operators.
