Summary

Correction to the spec of implicit negative subpattern in DecimalFormat

Problem

The DecimalFormat pattern contains positive and optional negative subpattern separated by ';' (For example, "#,##0.00;(#,##0.00)"), if negative subpattern is missing, then the positive pattern prefixed by the ASCII minus sign ('-' U+002D HYPHEN-MINUS) is used, which is incorrectly mentioned as "localized minus sign" in the specification.

Solution

Update the DecimalFormat specification to correctly mention the use of ASCII minus sign ('-' U+002D HYPHEN-MINUS) instead of "localized minus sign" for the implicit negative subpattern.

Specification

Update the DecimalFormat specification

from:

 * <p>A {@code DecimalFormat} pattern contains a positive and negative
 * subpattern, for example, {@code "#,##0.00;(#,##0.00)"}.  Each
 * subpattern has a prefix, numeric part, and suffix. The negative subpattern
 * is optional; if absent, then the positive subpattern prefixed with the
 * localized minus sign ({@code '-'} in most locales) is used as the
 * negative subpattern. That is, {@code "0.00"} alone is equivalent to
 * {@code "0.00;-0.00"}.
