NAME
|
|
sinh - hyperbolic sine
|
|
|
|
SYNOPSIS
|
|
sinh(x [,eps])
|
|
|
|
TYPES
|
|
x real
|
|
eps 0 < real < 1, defaults to epsilon()
|
|
|
|
return real
|
|
|
|
DESCRIPTION
|
|
Calculate the sinh of x to the nearest or next to nearest multiple of
|
|
epsilon, with absolute error less than .75 * abs(eps).
|
|
|
|
sinh(x) = (exp(x) - exp(-x))/2
|
|
|
|
EXAMPLE
|
|
; print sinh(1, 1e-5), sinh(1, 1e-10), sinh(1, 1e-15), sinh(1, 1e-20)
