2014-09-04erts: Correct conversion of MIN_SMALL numeral to fixnumSverker Eriksson
list_to_integer and binary_to_integer returned un-normalized bignum for -134217728 on 32-bit and -576460752303423488 on 64-bit. Thanks to Jesper Louis Andersen, Mikael Pettersson and Anthony Ramine for report, initial patch and optimization suggestion.
2013-09-09Fix incorrect values returned by integer_to_binary/2Juan Jose Comellas
When integer_to_binary/2 receives 0 or a negative number as an argument with a base that is different from 10, it will return incorrect values (<<>> in the case of 0) or it will crash (with negative numbers). This commit fixes these problems and adds tests to cover these cases.

2013-02-07float_to_list/2 changed rounding and cosmetic cleanupSerge Aleynikov
Changed rouding to round half-way up instead of down. Cosmetic cleanup and error handling of additional edge cases.

2013-01-21Text representation of a float formatted using given options.Serge Aleynikov
This BIF solves a problem of float_to_list/1 that doesn't allow specifying the number of digits after the decimal point when formatting floats. float_to_list(Float, Options) -> string() Float = float() Options = [Option] Option = {decimals, Decimals::0..249} | {scientific, Decimals::0..249} | compact Returns a string which corresponds to the text representation of a `Float` formatted using given options. When decimals option is specified the returned value will contain at most `Decimals` number of digits past the decimal point. When `compact` option is provided the trailing zeros at the end of the list are truncated (this option is only meaningful together with the `decimals` option). When `scientific` option is provided, the float will be formatted using scientific notation with `Decimals` digits of precision. If `Options` is `[]` the function behaves like `float_to_list/1`. When using `decimals` option and the number doesn't fit in the static internal buffer of 256 bytes the function throws `badarg`.
