If m is Infinity, return the string "Infinity". + 5. Otherwise, let n, k, and s be integers such that + k >= 1, 10k1 <= s < 10k, the number value for s10nk + is m, and k is as small as possible. Note that k is + the number of digits in the decimal representation + of s, that s is not divisible by 10, and that the + least significant digit of s is not necessarily + uniquely determined by these criteria. + 6. If k <= n <= 21, return the string consisting of the + k digits of the decimal representation of s (in order, + with no leading zeroes), followed by n-k occurences + of the character '0'. + 7. If 0 < n <= 21, return the string consisting of the + most significant n digits of the decimal + representation of s, followed by a decimal point + '.', followed by the remaining kn digits of the + decimal representation of s. + 8. If 6 < n <= 0, return the string consisting of the + character '0', followed by a decimal point '.', + followed by n occurences of the character '0', + followed by the k digits of the decimal + representation of s. + 9. Otherwise, if k = 1, return the string consisting + of the single digit of s, followed by lowercase + character 'e', followed by a plus sign '+' or minus + sign '' according to whether n1 is positive or + negative, followed by the decimal representation + of the integer abs(n1) (with no leading zeros). + 10. Return the string consisting of the most significant + digit of the decimal representation of s, followed + by a decimal point '.', followed by the remaining k1 + digits of the decimal representation of s, followed + by the lowercase character 'e', followed by a plus + sign '+' or minus sign '' according to whether n1 is + positive or negative, followed by the decimal + representation of the integer abs(n1) (with no + leading zeros). + + Note that if x is any number value other than 0, then + ToNumber(ToString(x)) is exactly the same number value as x. + + As noted, the least significant digit of s is not always + uniquely determined by the requirements listed in step 5. + The following specification for step 5 was considered, but + not adopted: + + Author: christine@netscape.com + Date: 10 july 1997 +*/ + +var SECTION = "9.8.1"; +var VERSION = "ECMA_1"; +startTest(); + +writeHeaderToLog( SECTION + " ToString applied to the Number type"); + +new TestCase( SECTION, "Number.NaN", "NaN", Number.NaN + "" ); +new TestCase( SECTION, "0", "0", 0 + "" ); +new TestCase( SECTION, "-0", "0", -0 + "" ); +new TestCase( SECTION, "Number.POSITIVE_INFINITY", "Infinity", Number.POSITIVE_INFINITY + "" ); +new TestCase( SECTION, "Number.NEGATIVE_INFINITY", "-Infinity", Number.NEGATIVE_INFINITY + "" ); +new TestCase( SECTION, "-1", "-1", -1 + "" ); + +// cases in step 6: integers 1e21 > x >= 1 or -1 >= x > -1e21 + +new TestCase( SECTION, "1", "1", 1 + "" ); +new TestCase( SECTION, "10", "10", 10 + "" ); +new TestCase( SECTION, "100", "100", 100 + "" ); +new TestCase( SECTION, "1000", "1000", 1000 + "" ); +new TestCase( SECTION, "10000", "10000", 10000 + "" ); +new TestCase( SECTION, "10000000000", "10000000000", 10000000000 + "" ); +new TestCase( SECTION, "10000000000000000000", "10000000000000000000", 10000000000000000000 + "" ); +new TestCase( SECTION, "100000000000000000000","100000000000000000000",100000000000000000000 + "" ); + +new TestCase( SECTION, "12345", "12345", 12345 + "" ); +new TestCase( SECTION, "1234567890", "1234567890", 1234567890 + "" ); + +new TestCase( SECTION, "-1", "-1", -1 + "" ); +new TestCase( SECTION, "-10", "-10", -10 + "" ); +new TestCase( SECTION, "-100", "-100", -100 + "" ); +new TestCase( SECTION, "-1000", "-1000", -1000 + "" ); +new TestCase( SECTION, "-1000000000", "-1000000000", -1000000000 + "" ); +new TestCase( SECTION, "-1000000000000000", "-1000000000000000", -1000000000000000 + "" ); +new TestCase( SECTION, "-100000000000000000000", "-100000000000000000000", -100000000000000000000 + "" ); +new TestCase( SECTION, "-1000000000000000000000", "-1e+21", -1000000000000000000000 + "" ); + +new TestCase( SECTION, "-12345", "-12345", -12345 + "" ); +new TestCase( SECTION, "-1234567890", "-1234567890", -1234567890 + "" ); + +// cases in step 7: numbers with a fractional component, 1e21> x >1 or -1 > x > -1e21, +new TestCase( SECTION, "1.0000001", "1.0000001", 1.0000001 + "" ); + +// cases in step 8: fractions between 1 > x > -1, exclusive of 0 and -0 + +// cases in step 9: numbers with 1 significant digit >= 1e+21 or <= 1e-6 + +new TestCase( SECTION, "1000000000000000000000", "1e+21", 1000000000000000000000 + "" ); +new TestCase( SECTION, "10000000000000000000000", "1e+22", 10000000000000000000000 + "" ); + +// cases in step 10: numbers with more than 1 significant digit >= 1e+21 or <= 1e-6 + +new TestCase( SECTION, "1.2345", "1.2345", String( 1.2345)); +new TestCase( SECTION, "1.234567890", "1.23456789", String( 1.234567890 )); + + +new TestCase( SECTION, ".12345", "0.12345", String(.12345 ) ); +new TestCase( SECTION, ".012345", "0.012345", String(.012345) ); +new TestCase( SECTION, ".0012345", "0.0012345", String(.0012345) ); +new TestCase( SECTION, ".00012345", "0.00012345", String(.00012345) ); +new TestCase( SECTION, ".000012345", "0.000012345", String(.000012345) ); +new TestCase( SECTION, ".0000012345", "0.0000012345", String(.0000012345) ); +new TestCase( SECTION, ".00000012345", "1.2345e-7", String(.00000012345)); + +new TestCase( SECTION, "-1e21", "-1e+21", String(-1e21) ); + +test(); + |
