HP 35s Scientific 1-22 Getting Started, Scientific Format (), Engineering Format ()

Scientific Format ()

SCI format displays a number in scientific notation (one digit before the "" or "" radix mark) with up to 11 decimal places and up to three digits in the exponent. After the prompt, _, type in the number of decimal places to be displayed. For 10 or 11 places, press or . (The mantissa part of the number will always be less than 10.)

For example, in the number , the "2", "3", "4", and "6" are the decimal digits you see when the calculator is set to SCI 4 display mode. The "5" following the "E" is the exponent of 10: 1.2346 ⋅ 105.

If you enter or calculate a number that has more than 12 digits, the additional precision is not maintained.

Engineering Format ()

ENG format displays a number in a manner similar to scientific notation, except that the exponent is a multiple of three (there can be up to three digits before the "" or "" radix mark). This format is most useful for scientific and engineering calculations that use units specified in multiples of 103 (such as micro–, milli–, and kilo–units.)

After the prompt, _, type in the number of digits you want after the first significant digit. For 10 or 11 places, press or .

For example, in the number , the "2", "3", "4", and "6" are the significant digits after the first significant digit you see when the calculator is set to ENG 4 display mode. The "3" following the "" is the (multiple of 3) exponent of 10: 123.46 x 103.,

Pressing @or 2will cause the exponent display for the number being displayed to change in multiples of 3, with the mantissa adjusted accordingly.
