+   File Name:          11.5.2.js
+   ECMA Section:       11.5.2 Applying the / operator
+   Description:
+
+   The / operator performs division, producing the quotient of its operands.
+   The left operand is the dividend and the right operand is the divisor.
+   ECMAScript does not perform integer division. The operands and result of all
+   division operations are double-precision floating-point numbers.
+   The result of division is determined by the specification of IEEE 754 arithmetic:
+
+   If either operand is NaN, the result is NaN.
+   The sign of the result is positive if both operands have the same sign, negative if the operands have different
+   signs.
+   Division of an infinity by an infinity results in NaN.
+   Division of an infinity by a zero results in an infinity. The sign is determined by the rule already stated above.
+   Division of an infinity by a non-zero finite value results in a signed infinity. The sign is determined by the rule
+   already stated above.
+   Division of a finite value by an infinity results in zero. The sign is determined by the rule already stated above.
+   Division of a zero by a zero results in NaN; division of zero by any other finite value results in zero, with the sign
+   determined by the rule already stated above.
+   Division of a non-zero finite value by a zero results in a signed infinity. The sign is determined by the rule
+   already stated above.
+   In the remaining cases, where neither an infinity, nor a zero, nor NaN is involved, the quotient is computed and
+   rounded to the nearest representable value using IEEE 754 round-to-nearest mode. If the magnitude is too
+   large to represent, we say the operation overflows; the result is then an infinity of appropriate sign. If the
+   magnitude is too small to represent, we say the operation underflows and the result is a zero of the appropriate
+   sign. The ECMAScript language requires support of gradual underflow as defined by IEEE 754.
