Dec 13, 2014 · FLT_MIN is not 0, it's just above 0, you just need to show more places to see that.FLT_MIN is the smallest floating point number above 0 that the computer can represent, since floating points are almost always an approximation, printf and friends round when printing, unless you ask it for the precision:

Apr 6, 2018 · Can someone explain why this outputs 0.000000 for both of the variables "area" and "peri"? int main() { double length, width, peri = (length*2) + (width*2), area ...

Mar 23, 2014 · Basically because if you interpret the bits that make up a small integer as if they were a double, it looks like the double value for 0.

Jan 13, 2018 · Assuming the assignment is to exclude all strings that consist entirely of zero's, at most one decimal point and possibly leading and/or trailing spaces, here is one way to do it, which requires only standard string functions (and therefore should be faster than any regular-expression solution).

Jan 26, 2017 · I would like to know why the output in this program is 0.0000: { int a = 65; char c = (char)a; int m = 3.0/2; printf("%f\n", 5 / 2); return (0); }

May 4, 2017 · @912M0FR34K: The main function is the entry point for the program, called by the execution environment. The language specification requires main to return an int value.

Feb 1, 2011 · Just because a number displays as "0.000000" does not mean it is equal to 0.0. The decimal display of numbers has less precision than a double can store.

Jul 22, 2013 · I would like to handle the decimal values 0.000000 and NULL in null-able column both as NULL For example: case worthColumn WHEN '0.000000' then NULL WHEN NULL then NULL ELSE worthColumn END AS

Feb 11, 2017 · @valleymanbs: I see. But this does not make sense in a comment to another answer. Instead flag the question as dup (comment at the answer if you don't have the reps, higher rep users often appreciate such help to close).

Jun 21, 2018 · You defined your function as: float function(x){ return x; } If you want the function to take a float argument, you need to say so:
