Constant: most-positive-fixnum

The immediate integer closest to positive infinity. See Configuration.

Constant: most-negative-fixnum

The immediate integer closest to negative infinity.

These procedures augment the standard capabilities in Numerical operations.

Function: sinh z

Function: cosh z

Function: tanh z

Return the hyperbolic sine, cosine, and tangent of z

Function: asinh z

Function: acosh z

Function: atanh z

Return the inverse hyperbolic sine, cosine, and tangent of z

Function: $sqrt x

Function: $abs x

Function: $exp x

Function: $log x

Function: $sin x

Function: $cos x

Function: $tan x

Function: $asin x

Function: $acos x

Function: $atan x

Function: $sinh x

Function: $cosh x

Function: $tanh x

Function: $asinh x

Function: $acosh x

Function: $atanh x

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.

Function: $log10 x

Real-only base 10 logarithm.

Function: $atan2 y x

Computes (angle (make-rectangular x y)) for real numbers y and x.

Function: $expt x1 x2

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 $expt is not real.
