Results Format

Calculator results are displayed in the format set in the ‘Results Format’ option of the ‘Settings’ menu. The options are as follows:

General

Displays results as the shortest possible decimal value using fixed or scientific format. Trailing zeros are removed from the result and a decimal point appears only if necessary.

The total number of significant figures in the result, excluding trailing zeros which are not displayed, is determined by the value set in the ‘Significant Figures’ control at the bottom of the Calculator’s main form.

Results are displayed using fixed point format if the number of digits to the left of the decimal point is less than or equal to the value set in the ‘Significant Figures’ control and if the result is greater than or equal to 0.00001. Otherwise results are displayed in scientific format.

Fixed Point

Displays results in the format "-ddd.ddd...". Results start with a minus sign if the number is negative, and at least one digit always precedes the decimal point.

The total number of digits in the result is set in the ‘Significant Figures’ control at the bottom of the Calculator’s main form.

If the number of digits to the left of the decimal point is greater than the value specified in this control, results are displayed in scientific format.

Number

Results are displayed in the form "-d,ddd,ddd.ddd...". This format is similar to the Fixed Point format, except that results contain thousand separators.

Scientific (standard form)

Results are displayed in the form "-d.ddd...E+dddd". Results start with a minus sign if the number is negative and one digit always precedes the decimal point.

The number of significant figures in the result is determined by the value set in the ‘Significant Figures’ control at the bottom of the Calculator’s main form.

The "E" exponent character is always followed by a plus or minus sign.

Hexadecimal

Hexadecimal is a base 16 number system where 16 digits are used instead of 10 to represent numbers. In addition to the standard base 10 system numbers 0-9, letters A-F are used to represent the numbers 10-15. Thus, a one digit hexadecimal number is a value between 0 and 15 (where F is 15). A two digit hex number is a value between 0 and 255 (represented as 00 and FF in hex, where 00 is 0*16 + 0*1, and FF is 15*16 + 15*1), and so forth.

Hexadecimal numbers are often used to represent data because they are easily translatable to base 2 numbers, the so-called binary system used by the electronic devices that are in computers.
