I'm just starting so excuse my ignorance. anyway, I'm trying to write a simple math program which computes the value of a trigonometric function. Basically just input one value and get another out, but I have two problems:
1. even with cmath included, the constant pi is not provided(I tried PI)
2. I can't seem to input values in the form of division ie 1/2, pi/3. I declared the input variable type double so does that mean you can't enter fractions during cin?
btw, I'm using Dev C++ V4.9.9.2

Code:const double PI=3.141414;

For PI, include <math.h> and reference M_PI.
You won't be able to input fractions and have the expression evaluated as part of the cin processing. Doesn't work that way.
if you input the fraction as a string you can, but there are no spaces and you have to convert it yourself. if you input it as an int/float/double it will read up to the first non-numerical character.
