The HP 9S calculator has an accuracy of 1 in the tenth digit.
In general, calculations can be displayed as a mantissa of up to ten digits, a tendigit mantissa together with a twodigit exponent up to 10^{±99}, or as an integer between 9999999999 and 9999999999.
Numbers used as input to a particular function must be within the allowable range for that function (as specified in the following table):
