I think the issue was by ths following , When you print out the difference, you also remove the value of total_extra. Thus, let's say diffrence = 0.47 and total_extra = 1. The difference is indeed positive (thus printing "Profit", but when you print the value difference - total_extra, you print out "-0.53"

wish help you to fix your issue float is a primitive data type and not an object. null check is used for objects. For primitives you should use the default values check. For float the default value is 0.0f.

Any of those help You can use %+f to make sure the sign (+ or -) is output (though - will be output regardless). So I think it is guaranteed for normal float values.
My only concern was about special values: inf and nan. So I've added printing p to the output and made an experiment. Here is what I've got with gcc 6.3:
code :
printf("IsNegative: %d\n", isNegative(+1.0/+0.0));
printf("IsNegative: %d\n", isNegative(-1.0/+0.0));
printf("IsNegative: %d\n", isNegative(+0.0/+0.0));
printf("IsNegative: %d\n", isNegative(+0.0/-0.0));
printf("IsNegative: %d\n", isNegative(-0.0/+0.0));
printf("IsNegative: %d\n", isNegative(-0.0/-0.0));
p = +inf
IsNegative: 0
p = -inf
IsNegative: 1
p = -nan
IsNegative: 1
p = -nan
IsNegative: 1
p = -nan
IsNegative: 1
p = -nan
IsNegative: 1
