1. ## The mathematical function library in C++

I have just started c++ and after collecting some tens of books i want to write some programmes different from what books have already.But when i want to write codes its quite hard for me.For example;i could hardly find below information but its not enough;how can i find whole lists of functions of standart libraries like math library.

Some of the mathematical functions available in the C++ mathematics library are listed below;

acos(x) inverse cosine, -1 <= x <= +1, returns value in radians in range 0 to PI
asin(x) inverse sine, -1 <= x <= +1, returns value in radians in range 0 to PI
atan(x) inverse tangent, returns value in radians in range -PI/2 to PI/2
cos(x) returns cosine of x, x in radians
sin(x) returns sine of x, x in radians
tan(x) returns tangent of x, x in radians
exp(x) exponential function, e to power x
log(x) natural log of x (base e), x > 0
sqrt(x) square root of x, x >= 0
fabs(x) absolute value of x
floor(x) largest integer not greater than x
ceil(x) smallest integer not less than x

2. Thanks a lot man....its really helpfull.but to say the truth i dont know for wat i should want to pres any key for some hundred times

3. Lol, that's my sig, not my post.
