**Why Is There No Negative Zero**. Answered nov 16, 2010 at 22:46. Strict equality comparison using === aka “triple equals”;

Sum of a number and its negative number is always zero, 0. Python on the mac supports negative zero for floats, but throws an exception when you attempt to divide by zero of any sign. Q) why is there no zero positive and negative number?

### Which Is Why The === Operator Here Works.

The system can then be characterised as having a negative. Why are there negative temperatures? Therefore, zero needs to be in a class.

### So This Messes Things Up.

0000 0000 so a minus 0 should look. Answered nov 16, 2010 at 22:46. However, in computing, some number representations allow for the existence of two zeros, often denoted by −0 (negative zero) and +0 (positive zero), regarded as equal by the numerical comparison operations but with possible different.

### So, There Was No Need For A Symbol To Represent Zero.

Why does the product of an integer multiplied by itself cannot be negative? Python on the mac supports negative zero for floats, but throws an exception when you attempt to divide by zero of any sign. One can admit that zero has no sign.

### I Will Give It A Try Nonethe.

Float.epsilon is the smallest positive value representable by a float.this means that there is no float less than it which is positive.yes, you could (and should) be using double, which can represent much smaller numbers, but the main issue remains: There are some good answers here, and they are all right in a way. Floating point numbers have scaling resolution, meaning.

### Python On The Mac Supports Negative Zero For Floats, But Throws An Exception When You Attempt To Divide By Zero Of Any Sign.

In this sense, zero isn't negative (nor positive for a similar reason). In other words, try to hide the fact that there is a negative zero. For a binary integer, setting the sign bit to 1 and all other bits to zero, you get the smallest negative value for that integer size.
