d2q(x)
q2d(x)
q2q(x)
z2q(numer, denom, canonicalize = TRUE)

Arguments

`x,numer,denom`	objects of type `"numeric"` or `"character"`.
`canonicalize`	if `TRUE` (the default) canonicalize (see below).

Value

d2q converts from real to rational, q2d converts from rational to real, q2q canonicalizes (no common factors in numerator and denominator) rationals, z2q converts integer numerator and denominator to rational canonicalizing if canonicalize = TRUE (the default).

Examples

d2q(runif(1))
q2d("-123456789123456789987654321/33")
