3d ploting function z = f(x,y)

parser features:
arguments : x,y
r == sqrt( x*x + y*y )
+ - * / ( )   -  no comments
|x| == abs(x)
[x] == int(x)
{x} == x - [x]
functions : sin(x), cos(x), tan(x), exp(x), ln(x), lg(x),
min(x1,x2,...), max(x1,x2,...), sqr(x), sqrt(x).

samples of expression :
sin(r*r)
sin(x*x-y*y)
1/[r]
