Peter Wang	bfe14f9128	Fix string.base_string_to_int succeeding incorrectly. ... string.base_string_to_int would incorrectly succeed on an input string containing a code point of multiple code units. string.foldl_between expects the length of the string in code units, but was passed the length of the string in code points. library/string.m: As above. tests/general/base_string_to_int_test.exp: tests/general/base_string_to_int_test.m: Extend test case.	2013-02-11 11:04:21 +11:00
Ian MacLarty	8d365b4056	Change string.base_string_to_int so that it doesn't fail if the base is 10 and ... the integer is int.min_int. The previous behaviour seems unintuitive and means we can't use the literal -2147483648 in Mercury programs on 32 bit machines, even though that number can be represented in 32 bits. library/string.m: If the integer to be parsed is negative, then use a negative accumulator, so that if the number is int.min_int it doesn't cause an overflow. tests/general/base_string_to_int_test.exp: tests/general/base_string_to_int_test.m: Test it.	2010-01-14 06:55:53 +00:00
Ralph Becket	e1c6ed1409	Added a test case for string.base_string_to_int/3. ... Estimated hours taken: 0.2 Branches: main tests/general/Mmakefile: tests/general/base_string_to_int.m: tests/general/base_string_to_int.exp: Added a test case for string.base_string_to_int/3.	2004-07-01 06:20:14 +00:00
