HP 32sII Scientific SHOWing Full 12–DigitPrecision, ALL Format ({}), 1–16Getting Started, Engineering Format ({})

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 "8" radix mark). This format is most useful for scientific and engineering calculations that use units specified in multiples of I03 (such ass 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 Œ0 or Œ1.

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 "E" is the (multiple of 3) exponent of 10: 123.46x 103.

ALL Format ({})

ALL format displays a number as precisely as possible (12 digits maximum). If all the digits don't fit in the display, the number is automatically displayed in scientific format: 123,456.

SHOWing Full 12–Digit Precision

Changing the number of displayed decimal places affects what you see, but it does not affect the internal representation of numbers. Any number stored internally always has 12 digits.

For example, in the number 14.8745632019, you see only "14.8746" when the display mode is set to FIX 4, but the last six digits ("632019") are present internally in the calculator.

To temporarily display a number in full precision, press {. This shows you the mantissa (but no exponent) of the number for as long as you hold down .
