HP 9G Calculator - Accuracy and Capacity

The HP 9G calculator uses up to ten digits for output, and up to 24 digits during calculations.
Where possible, calculations are displayed in up to ten digits, or as a ten-digit mantissa together with a two-digit exponent up to 10±99 .
Numbers used as input to a particular function must be within the allowable range for that function (as specified in the following table):
Functions
Allowable input range
sin x, cos x, tan x
Deg: |x| < 4.5 × 1010 deg
Rad: |x| < 2.5 × 108 rad
Grad: |x| < 5 × 1010 grad
Also, for tan x:
Deg: |x| 90 (2n + 1)
Rad: |x| /2 (2n + 1)
Grad: |x| 100 (2n + 1) where n is an integer.
