I'm trying to take some square roots, and I've simplified the code down to
main()
{
printf("%f\n", sqrt(144.));
}

but I'm still getting crazy numbers.

Make sure that you have #included <math.h>, and correctly declared other functions returning double. (Another library function to be careful with is atof, which is declared in <stdlib.h>.)

How do I round numbers?
How do I round numbers? The simplest and most straightforward way is with code like (int)(x + 0.5) C's floating to integer conversion truncates (discards) the fractional part, so adding 0.5 before truncating arranges that fractions >= 0.5 will be rounded up. (This technique won't work properl... 2015-06-26, 1897👍, 0💬

I am trying to do some simple trig...
I'm trying to do some simple trig, and I am #including <math.h>, but the linker keeps complaining that functions like sin and cos are undefined. Make sure you're actually linking with the math library. For instance, due to a longstanding bug in Unix and Linux systems, you usually need to use ... 2015-07-01, 1730👍, 0💬

I am sure I've got the trig functions declared correctly, but they are still giving me wrong answers.
I am sure I've got the trig functions declared correctly, but they are still giving me wrong answers. You weren't handing them angles in degrees, were you? C's trig functions (like FORTRAN's and most other languages) accept angles in radians. The conversion from degrees to radians is simple enough: ... 2015-06-29, 1714👍, 0💬

Why is my simple program, which hardly does more than print
Why is my simple program, which hardly does more than print ``Hello, world!'' in a window, compiling to such a huge executable (several hundred K)? Should I #include fewer header files? What you're seeing is the current (poor) state of the ``art'' in library design. As run-time libraries accrete mor... 2015-07-06, 1661👍, 0💬

I am still getting errors due to library functions being undefined
I'm still getting errors due to library functions being undefined, even though I'm explicitly requesting the right libraries while linking. Many linkers make one pass over the list of object files and libraries you specify, and extract from libraries only those modules which satisfy references which... 2015-07-14, 1598👍, 0💬

What does it mean when the linker says that _end is undefined?
What does it mean when the linker says that _end is undefined? That message is a quirk of the old Unix linkers. You get an error about _end being undefined only when other symbols are undefined, too--fix the others, and the error about _end will disappear. 2015-07-06, 1554👍, 0💬

When I set a float variable to, say, 3.1, why is printf printing it as 3.0999999?
When I set a float variable to, say, 3.1, why is printf printing it as 3.0999999? Most computers use base 2 for floating-point numbers as well as for integers, and just as for base 10, not all fractions are representable exactly in base 2. It's well-known that in base 10, a fraction like 1/3 = 0.333... 2015-07-03, 1548👍, 0💬

My compiler is complaining that printf is undefined! How can this be? It's the world's most popular C function... Allegedly, there are C compilers for Microsoft Windows which do n ot support printf, on the argument that printf is for printing to old-fashioned terminals, while under Windows the right... 2015-07-03, 1511👍, 0💬
