Mathematical, timer, and conversion functions

The mathematical, timer, and conversion functions were described in Chapter 6, Animating Parameters, and Chapter 7, Distributed and Physical Computing with Networking and Arduino, and are collected in this table:

Function	Description
ofMap( x, 0, 1, 2, 3 )	This linearly maps the float x from segment [0,1] to segment [2,3].
ofMap( x, 0, 1, 2, 3, true )	This linearly maps the float x from the segment [0,1] to the segment [2,3], clamping the output value to the [2,3] range (it occurs when x is not in segment [0,1]).
ofClamp( x, 0, 1 )	This clamps the float x to the range [0,1].
ofInRange( x, 0, 1 )	This returns true if the float x lies in the segment [0,1] and returns false in the opposite case.
ofToString( 0.5 )	This converts a numeric value (integer or float) to a string.
ofGetElapsedTime()	This is the number of seconds elapsed from the application start; the returned value is float.
ofNoise( x )	This is the Perlin...
