◆ BackupNumber()

static const char* BackupNumber ( const char Pos,
const char FirstChar 
)
static

Definition at line 53 of file FileUtilities.cpp.

References isExponentChar(), isNumberChar(), and isSignedChar().

Referenced by llvm::DiffFilesWithTolerance().

◆ CompareNumbers()

static bool CompareNumbers ( const char *&  F1P,
const char *&  F2P,
const char F1End,
const char F2End,
double  AbsTolerance,
double  RelTolerance,
std::string *  ErrorMsg 
)
static

CompareNumbers - compare two numbers, returning true if they are different.

Definition at line 84 of file FileUtilities.cpp.

◆ EndOfNumber()

static const char* EndOfNumber ( const char Pos)
static

EndOfNumber - Return the first character that is not part of the specified number.

This assumes that the buffer is null terminated, so it won't fall off the end.
