ReadDouble()

double ReadDouble	(	char *&	text,
		bool	aSkipSeparator = true
	)

Read a double precision floating point number from an ASCII character buffer.

If there is a comma after the number, then skip over that.

Parameters

text	is a reference to a character pointer from which the ASCII double is read from and the pointer advanced for each character read.
aSkipSeparator	set to true (default) to skip comma.

Returns

number read.

 // For strtod, a string starting by 0X or 0x is a valid number in hexadecimal or octal.
 // However, 'X' is a separator in Gerber strings with numbers.
 // We need to detect that
 if( strncasecmp( text, "0X", 2 ) == 0 )
 {
 text++;
 ret = 0.0;
 }
 else
 {
 ret = strtod( text, &text );
 }
 
 if( *text == ',' || isspace( *text ) )
 {

 ++text;
 }
 
 return ret;

ReadInt()

int ReadInt	(	char *&	text,
		bool	aSkipSeparator = true
	)

Read an integer from an ASCII character buffer.

If there is a comma after the integer, then skip over that.

Parameters

text	is a reference to a character pointer from which bytes are read and the pointer is advanced for each byte read.
aSkipSeparator	set to true (default) to skip comma.

Returns

The integer read in.
