CFStringGetIntValue and CFStringGetDoubleValue passed the whole string to the number formatter, which fails on leading whitespace and returned zero. Skip leading whitespace and parse from there.

CFStringGetIntValue and CFStringGetDoubleValue passed the whole string to the
number formatter, which does not accept leading whitespace, so a value such as
" 42" returned 0. Apple skips leading whitespace before parsing. Skip leading
whitespace and parse from the first non-whitespace character. Verified against
Apple CoreFoundation.
