About the book
Extensive, thorough, and useful, this
book provides methods and tabular
data for designing accurate function
subroutines.
It is extensive in its range in ac-
curacy from a few digits up to 25 D
in the approximations; in its wide
selection of functions, including
square root and cube root, exponen-
tial and hyperbolic, logarithm, trigo-
nometric and inverse trigonometric,
gamma function and its logarithm,
error function, Bessel functions and
complete elliptic integrals; and in
the range of methods the book de-
scribes and compares — from gen-
eral methods of subroutine design to
procedures for the design of maxi-
mum efficiency programs for com-
monly needed functions.
It is thorough in its attention to
such vital information as procedures
for obtaining the approximations,
how the approximations may be im-
proved in accuracy, and how ap-
proximations may be obtained for
functions not previously program-
med.
It is useful not only for the...

for obtaining the approximations,
how the approximations may be im-
proved in accuracy, and how ap-
proximations may be obtained for
functions not previously program-
med.
It is useful not only for the informa-
tion it offers but for its reliability (a
good many of the approximations
have been thoroughly tested in com-
puter programs) and its versatility (it
is a guide to both finding an initial
usable approximation and to obtain-
ing approximations of maximum ac-
curacy and efficiency).
