Hi !

Short question:

Is there a method/function for “casting” floats to integers ?

Something like ( int)(Math.sqrt(2)+1) ???

Thanks for any hint in advance !

Is there a method/function for "casting" floats to integers ?

Float#to_i, #ceil, #floor and #round

% ri Float.to_i
------------------------------------------------------------- Float#to_i
flt.to_i → anInteger

··· 
 Returns flt truncated to an Integer.

But it’s all right; I’m catching the next train home.

The difference between art and science is that science is what we understand
well enough to explain to a computer. Art is everything else.
