Accuracy and Capacity
Output digits : Up to 12 digits.
Calculating digits : Up to 14 digits
In general, every reasonable calculation is displayed up to 12 digits
mantissa, or 12-digits mantissa plus 2-digits exponent up to 10
± 99 .
Numbers used as input must be within the range of the given function
as follow :
Functions Input range
sin x
cos x
tan x Deg : x < 4.5 x 10 10 deg
Rad : x < 2.5 x 10 8 π rad
Grad : x < 5 x 10 10 grad
however, for tan x
Deg :
x ≠ 90 (2n+1)
Rad : x ≠
2
π
(2n+1)
Grad : x ≠ 100 (2n+1), (n is an integer)
sin –1 x, cos –1 x x ≦ 1
tan –1 x x < 1 x 10 100
sinh x, cosh x x ≦ 230.2585092
tanh x x < 1 x 10 100
sinh –1 x x < 5 x 10 99
cosh –1 x 1 ≦ x < 5 x 10 99
