Subject: json: handle capital floating point exponent (1E100).
X-Git-Tag: weekly.2011-02-01~100
X-Git-Url: http://www.git.cypherpunks.su/?a=commitdiff_plain;h=c4513d3b6fc67d1e0525b008c6b34fe536ee74b6;p=gostls13.git

json: handle capital floating point exponent (1E100).

When parsing numbers with an exponent (like "12e-1"), the JSON scanner
would only allow a lowercase 'e', while the RFC also allows the
uppercase 'E'.
