How to check if a number is negative.

In a function like that I suggest you go all out and compare with the octal number instead of a char ;)

...aaaaaand memory leak

@-eth I don't think that would make a big difference for such a codebase anyway

This hurts me on so many levels as a TA for a class that teaches C

kill it! kill it with fire!

There are so so so many problems with this.
It's painful 🙁

Don't let that breed or lay eggs

Nuke it.

Is there no managed if in C++?

I have been doing it wrong all this time...

return arg < 0;

LOL YES! 😂😂😂

Using the heap instead of the stack to create a fixed size array and not even free it afterwards, all that to sprintf the sign. I'm having a hard time thinking how to make it any worse. You are a genius! :)
Such efficient, much wow.

In the internal representation, there is 1 bit for the sign (S), 8 bits for the exponent (E), and 23 bits for the fraction (F). The bits are mapped with the fraction in bit 0 to bit 22, the exponent in bit 23 to bit 30, and the sign in bit 31.

so code:

static bool IsNagative (float numb)
{
if(numb >> 31)
{
return true;
}
return false;
}

no memory allocation needed and if you don't want a copy of the float variable then use references.

@xwing7 so you could basically do:
return num >> 31
