Summary |
0001395: awk radix character in alternative conversion to atof() |
|
Description |
In POSIX.2-1992 awk was required to convert string values to numeric values by the equivalent of:setlocale(LC_NUMERIC, "");
numeric_value = atof(string_value); Later when atof() was required to support hex floating point, "INF", and "NAN", this was changed to make the support of those new things optional in awk by saying the conversion is done either as above or by an alternative conversion that is a description of how atof() used to work in C90.
At least, that's what was intended. Unfortunately, the description of this alternative conversion refers to <period> instead of the radix character.

Desired Action |
On page 2486 line 79925 section awk, change:... optionally containing a <period> to:... optionally containing a radix character
On page 2486 line 79928 section awk, change:The sequence starting with the first digit or the <period> (whichever occurs first) is interpreted as a floating constant of the C language, and if neither an exponent part nor a <period> appears, a <period> is assumed to follow the last digit in the string. to:The sequence starting with the first digit or the radix character (whichever occurs first) is interpreted as a floating constant of the C language, except that the radix character shall be used in place of a <period>, and if neither an exponent part nor a radix character appears, a radix character is assumed to follow the last digit in the string.
