Problem type

Given the real coefficients $a$ ~a~ and $b$ ~b~ $(-1\,000 \le a, b \le 1\,000)$ ~(-1\,000 \le a, b \le 1\,000)~, solve for $x$ ~x~ in the following equation.

$\displaystyle ax + b = 0$ $a x + b = 0$

Be sure to output indeterminate and undefined whenever appropriate. Remember $\dfrac 0 0$ ~\dfrac 0 0~ is indeterminate, and something like $\dfrac 4 0$ ~\dfrac 4 0~ is undefined.

Output the value of $x$ ~x~ rounded to two decimal places.

Input Specification

The input consists of two real numbers, $a$ ~a~ and $b$ ~b~. $a$ ~a~ and $b$ ~b~ will be on separate lines, with $a$ ~a~ first, and $b$ ~b~ second.

Output Specification

Output the value of $x$ ~x~ according to the given values and equation. Be sure to output indeterminate and undefined whenever appropriate.

Note that a and b can be negative, -4 / 0 is still undefined, and your code doesn't output anything if either a or b is negative.

You have to print 2 decimal places.
