2014-01-23(PUP-1195) Fix is_numeric/is_integer when checking non-string parametersSimon Effenberg
I expect a function called "is_numeric" or "is_integer" to check if a variable is an integer or a number even if the variable passed by isn't a string nor a number at all. Otherwise we should call them is_string_a_number and is_string_an_integer and we have then to remove the check for .is_a?(Number) and .is_a?(FixNum) now checking also if it is a hex or octal number improved/corrected checking for integer * checking against Integer instead of Fixnum so that also Bignum is matching * now .is_a? Integer is done first so this is quiet fast Now many types of numerics are recognized. 1. Float/Integer values (signed or unsigned, with exponent or without) 2. octal and hex check 3. except hex numbers and the "0." in a float lower than 1 can be prefixed with a '0'. whitespaces shouldn't be allowed as prefix/suffix string representation of numbers should not contain any type of whitespace.. the user is responsible to clean a string before checking it.. fix documentation and added more checks tried to be 99.9% backward compatible * for now the decission is post poned if hex and octal numbers should be allowed or not (is_numeric) * native Bignum is now also a valid integer class fix problem with old 1.8 ruby and Hash.to_s/Array.to_s In ruby < 1.9 array and hashes would be recognized as numeric if they have a special format: 1.8: [1,2,3,4].to_s = "1234" {1=>2}.to_s = "12" 1.9: [1,2,3,4].to_s = "[1, 2, 3, 4]" {1=>2}.to_s = "{1=>2}"
