question: private boolean canonicalizeNumber ( int start , int end ) { elide ( start , start ) ; int sanStart = sanitizedJson . length ( ) ; normalizeNumber ( start , end ) ; elide ( end , end ) ; int sanEnd = sanitizedJson . length ( ) ; return canonicalizeNumber ( sanitizedJson , sanStart , sanEnd ) ; }
target:  Converts a run of characters that form a JS number to its canonical form which happens to also be a valid JSON number.
