5.3 Numeric
— Constant:
most-positive-fixnum
The immediate integer closest to positive infinity.
See Configuration.
— Constant:
most-negative-fixnum
The immediate integer closest to negative infinity.
— Constant:
$pi
— Constant:
pi
The ratio of the circumference to the diameter of a circle.
These procedures are in addition to those in
See Irrational Integer Functions.
— Function:
exact-round x
— Function:
exact-floor x
— Function:
exact-ceiling x
— Function:
exact-truncate x
Return exact integers.
These procedures augment the standard capabilities in
Numerical operations.
Many are from

— Function:
real-tan x
— Function:
real-asin x
— Function:
real-acos x
— Function:
real-atan x
— Function:
atan y x
— Function:
real-sinh x
— Function:
real-cosh x
— Function:
real-tanh x
— Function:
real-asinh x
— Function:
real-acosh x
— Function:
real-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:
real-log10 x
Real-only base 10 logarithm.
— Function:
$atan2 y x
Computes (angle (make-rectangular x y)) for real numbers y
and x.
— Function:
real-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 real-expt
is not real.
— Function:
infinite? z
— Function:
finite? z
All IEEE-754 numbers except positive and negative infinity and NaN
(non-a-number) are finite.
