Given a real or complex input, this function returns the value of that input multiplied by -1. Given a matrix or vector, this function returns a matrix or vector of the same dimension with each value multiplied by -1.

Note that the CHS (change sign) button on the calculator executes the NEG operation on the top item on the stack. However, if you press CHS while in the midst of entering something, it does not execute CHS and instead tries to negate the current entry without pushing it to the stack.
