(conjugate z)      PROCEDURE

Returns the complex conjugate of z.

(cosh z)      PROCEDURE

Returns the hyperbolic cosine of z.

e      NUMBER

Approximation of Euler's number, equivalent to (exp 1.0).

pi      NUMBER

Approximation of pi, equivalent to (atan 0.0 -1.0).

(sinh z)      PROCEDURE

Returns the hyperbolic sine of z.

(sgn n)      PROCEDURE

Returns 1 if n is positive, -1 if n is negative, and 0 otherwise. If n is exact, the result is exact, otherwise the result is inexact.
