ofToString ()

string ofToString(const T &value)

Convert a value to a string.

ofToString does its best to convert any value to a string. If the data type implements a stream << operator, then it will be converted.

Example:

std::string str = "framerate is ";
str += ofToString(ofGetFrameRate()) + " fps";
// The string now containes something like "framerate is 60 fps".

Template Parameters

T	The data type of the value to convert to a string.

Parameters

value The value to convert to a string.

Returns: A string representing the value or an empty string on failure.

string ofToString(const T &value, int precision)

Convert a value to a string with a specific precision.

Like sprintf "%4f" format, in this example precision=4

Template Parameters

T	The data type of the value to convert to a string.

Parameters

value	The value to convert to a string.
precision	The precision to use when converting to a string.

Returns: The string representation of the value.

string ofToString(const T &value, int width, char fill)

Convert a value to a string with a specific width and fill.

Like sprintf "% 4d" or "% 4f" format, in this example width=4, fill=' '

Template Parameters
