Problem with math.h pow

[void]

I just noticed something problematic with the pow.

pow (10, 2)

This returns 100. Normal

(Unsigned short) pow (10, 2)

This returns 99.

Can anyone explain why?

Use static_cast Operator. It converts expression to the type of type-id based solely on the types present in the expression.

[void]

# include <iostream> 
# include <math.h> 

template <typename Type> 
void myfunc () 
{ 
      std:: cout <<static_cast <unsigned short> (pow (10, 2)) <<std:: endl; 

      for (unsigned short i = 0; i <3; i + +) 
          if (i == 2) 
               std:: cout <<static_cast <Type> (pow (10, i)) <<std:: endl; 
}

int main () 
{ 
      Myfunc <unsigned short> (); 
}

It's really strange
