Exponential Operator in C++

Question

I am taking a class in C++ and I noticed there are only a few math operators to use. I also noticed that C++ does not come with an exponential operator within its math libr

Answer 1

According to Bjarne Stroustrup in his book The design and evolution of C++. They decided to avoid exponential operator because :

• An operator provides notational convenience, but does not provide any new functionality. Members of the working group, representing heavy users of scientific/engineering computation, indicated that the operator syntax provides minor syntactic convenience.
• Every user of C++ must learn this new feature
• Users have stressed the importance of susbtituting their own specialized exponentiation functions for the system default, which would not be possible with an intrinsic operator
• The proposal is not sufficiently well motivated. In particular, by looking at one 30000 line Fortran program one cannot conclude that the operator would be widely used in C++
• The proposal requires adding a new operator and adding another precedence level thus increasing the complexity of the language
