None.

Mathematical Rules


Multiplication Rules
NEGATIVE_INFINITY*POSITIVE_INFINITY=NEGATIVE_INFINITY
NEGATIVE_INFINITY*any other positive value=NEGATIVE_INFINITY
NEGATIVE_INFINITY*NEGATIVE_INFINITY=POSITIVE_INFINITY
NEGATIVE_INFINITY*any other negative value=POSITIVE_INFINITY
NEGATIVE_INFINITY*zero=NaN
NEGATIVE_INFINITY*NaN=NaN
 
Division Rules
NEGATIVE_INFINITY/NEGATIVE_INFINITY=NaN
NEGATIVE_INFINITY/any other negative value=POSITIVE_INFINITY
NEGATIVE_INFINITY/POSITIVE_INFINITY=NaN
NEGATIVE_INFINITY/any other positive value=NEGATIVE_INFINITY
any number/NEGATIVE_INFINITY=zero

Examples

The code below displays the above NEGATIVE_INFINITY rules.


// Multiplication Rules
var negInfinityMult = new Array(6);
negInfinityMult[0] = Number.NEGATIVE_INFINITY * Number.POSITIVE_INFINITY;
negInfinityMult[1] = Number.NEGATIVE_INFINITY * Number.MIN_VALUE;
negInfinityMult[2] = Number.NEGATIVE_INFINITY * Number.NEGATIVE_INFINITY;
negInfinityMult[3] = Number.NEGATIVE_INFINITY * (Number.MIN_VALUE * -1);
negInfinityMult[4] = Number.NEGATIVE_INFINITY * 0;
negInfinityMult[5] = Number.NEGATIVE_INFINITY * Number.NaN;
alert('Multiplication Results: ' + negInfinityMult);
// Division Rules
var negInfinityDiv = new Array(7);
negInfinityDiv[0] = Number.NEGATIVE_INFINITY / Number.NEGATIVE_INFINITY;
negInfinityDiv[1] = Number.NEGATIVE_INFINITY / (Number.MIN_VALUE * -1);
negInfinityDiv[2] = Number.NEGATIVE_INFINITY / Number.POSITIVE_INFINITY;
negInfinityDiv[3] = Number.NEGATIVE_INFINITY / Number.MIN_VALUE;
negInfinityDiv[4] = -1 / Number.NEGATIVE_INFINITY;
negInfinityDiv[5] = 0 / Number.NEGATIVE_INFINITY;
negInfinityDiv[6] = 1 / Number.NEGATIVE_INFINITY;
alert('Division Results: ' + negInfinityDiv);
