|
|
|
|
SYNOPSIS
|
|

|
|
|
|
TYPES
|
|
x real

return integer

|
DESCRIPTION
|
|
For real x, den(x) returns the denominator of x. In calc,
|
|
real values are actually rational values. Each calc real
|
|
value can be uniquely expressed as:
|
|
|
|
n / d
|
|
|
|
where:
|
|
|
|
n and d are integers
|
|
gcd(n,d) == 1
|
|
d > 0
|
|
|
|
If x = n/x, then den(x) == n.
