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. + + Author: christine@netscape.com + Date: 12 november 1997 +*/ +var SECTION = "11.5.2"; +var VERSION = "ECMA_1";
