I am working with a software (Oracle Siebel) that only supports Javascript expressions with operators multiply, divide, subtract, add, and XOR (*, /, -, +, ^). I don't have other operators such as ! or ?: available.

Using the above operators, is it possible to convert a number to 1 if it is non-zero and leave it 0 if it's already zero? The number may be positive, zero, or negative.

Example:

`var c = 55; var d; // d needs to set as 1 `

I tried `c / c`

, but it evaluates to `NaN`

when `c`

is 0. `d`

needs to be 0 when `c`

is 0.

c is a currency value, it will have a maximum of two trailing digits and 12 leading digits.

I am trying to emulate an if condition by converting a number to a boolean 0 or 1, and then multiplying other parts of the expression.

`c / (c + 5e-324)`

should work. If x is 0, that is exactly 0, and if x is nonzero (technically, if x is at least 4.45014771701440252e-308, which the smallest non-zero number allowed in the question, 0.01, is), JavaScript's floating-point math is too imprecise for the answer to be different than 1, so it will come out as exactly 1.
