Usage

From source file:unikl.disco.misc.NumberObj.java

public static NumberObj div(NumberObj num1, NumberObj num2) {
    if (performTypeChecks) {
        TypeCheck(num1, num2);/*from   w  w  w  .j  av a 2s. c  om*/
    }

    if (num1.equals(NaN) || num2.equals(NaN)) {
        return NaN;
    }
    // Integer based number representations use Integer.MAX_VALUE to signal infinity so special treatment is necessary when dividing
    if (num1.equals(POSITIVE_INFINITY)) {
        return POSITIVE_INFINITY;
    }
    if (num2.equals(POSITIVE_INFINITY)) {
        return new NumberObj(0.0);
    }
    if (num1.equals(NEGATIVE_INFINITY)) {
        return NEGATIVE_INFINITY;
    }
    if (num2.equals(NEGATIVE_INFINITY)) {
        return new NumberObj(0.0);
    }

    switch (num1.getType()) {

    case RATIONAL:
