The immediate integer closest to positive infinity. See Configuration in SLIB.
The immediate integer closest to negative infinity.
The ratio of the circumference to the diameter of a circle.
These procedures are in addition to those in See Irrational Integer Functions in SLIB.
Return exact integers.
These procedures augment the standard capabilities in Numerical operations in Revised(5) Scheme. Many are from See Irrational Real Functions in SLIB.
(* pi z)
(/ pi z)
Return the hyperbolic sine, cosine, and tangent of z
Return the inverse hyperbolic sine, cosine, and tangent of z
Real-only versions of these popular functions. The argument x must be a real number. It is an error if the value which should be returned by a call to these procedures is not real.
Real-only base 10 logarithm.
(angle (make-rectangular x y)) for real numbers y
Returns real number x1 raised to the real power x2. It is
an error if the value which should be returned by a call to
is not real.
All IEEE-754 numbers except positive and negative infinity and NaN (non-a-number) are finite.
