Attributes for controlling numerical evaluation.
|NHoldAll ||prevent any arguments of a function from being affected by N |
|NHoldFirst ||prevent the first argument from being affected |
|NHoldRest ||prevent all but the first argument from being affected |
|Usually N goes inside functions and gets applied to each of their arguments. || |
|This tells Mathematica not to apply N to the first argument of f. || |
|Now the first argument of f is left in its exact form. || |
