argument x, [NewRat](a, b) returns a *[Rat] set to the fraction a/b where
a and b are int64 values, and [NewFloat](f) returns a *[Float] initialized
to the float64 argument f. More flexibility is provided with explicit
setters, for instance:

	var z1 Int
	z1.SetUint64(123)                 // z1 := 123
	z2 := new(Rat).SetFloat64(1.25)   // z2 := 5/4
	z3 := new(Float).SetInt(z1)       // z3 := 123.0

without a format or with the %v verb, as are digit-separating
underscores.

Width is interpreted in the input text but there is no
syntax for scanning with a precision (no %5.2f, just %5f).
If width is provided, it applies after leading spaces are
trimmed and specifies the maximum number of runes to read
to satisfy the verb. For example,

	Sscanf(" 1234567 ", "%5s%d", &s, &i)

will set s to "12345" and i to 67 while

grep [-count=N] [-q] 'pattern' file
	find lines in a file that match a pattern

	The command succeeds if at least one match (or the exact
