This is a simple calculator which has the following functionalities :
1. You can declare your own variables (single letter from a to z).
2. Variable declaration and initilization can be done simultaneously.
3. Following operations are currently supported :
+ addition like a+b or a+10 or 12+13
- subtraction like a-(b*c) or a-10 or 12-13
* multiplication like a*(b+c) or a*12 or 12*13
/ division like a/(b+c or a/12 or 12/(13+a)
^ power like 10^x or 12^3 or 12^(a+b)
exp(x) e^x
fac(x) factorial of x
ln(x) log(x) to the base e
log(x) log(x) to the base 10
sin(x) trigonometric sin where x is in degree
cos(x) trigonometric cos where x is in degree
tan(x) trigonometric tan where x is in degree
asin(x) trigonometric arc sin
acos(x) trigonometric arc cos
atan(x) trigonometric arc tan
4. Each statement or declaration should be in different lines.
All numeric operations are done in floating point.
For invalid input (operation like /, exp, fac, ln, log, sin, cos, tan, asin, acos, atan)
NaN, Infinity or division by zero (Infinity) may be returned.
Each input line has a corresponding output line which gives the desired result.
Sample calculation :
--------------------
a=12
b=13
(a+b)*(34*ln(exp(a*b-10*(1+2))))
c=2
d=a/(c+8)
d
c=0
d/c
Output :
--------
12.0
13.0
107100.0
2.0
1.2
1.2
c=0.0
Infinity --->division by 0
Limitations :
1. Strict syntax checking is not done.
2. Error messages are not clearly specified in some cases.
