Formulas - Multiplying a value by -1 always gives back -1 as an answer.

[axyl]

In a formula, if you multiply a value by a negative number, the answer is always the negative number you used.

$value= (20 * -10);
output\printLine($value);

Returns -10;

$value= (20 * -1);
output\printLine($value);

Returns -1;

Do other people get this too? Confirm it in the Formula Sandbox.

Use parentheses. * (-10)

I think we had a similar bug report about this.

Use this as workaround:

$value= (20 * (-10));
output\printLine($value);

[shalmaxb]

these work both

[your field] = -(20*10)

[your field]= 20*(-10);
