WWW.DATEXX.COM FEATURES Large 10 + 2 Digit Display Calculates Mixed and Improper Fractions Up to 15 levels of Parenthesis Binary / Octal / Decimal / Hexadecimal Calculation Modes Common and Natural Logarithms Advanced Statistical Functions Boolean Logic calculations Auto Power off saves batteries Battery powered Protective Case Folding stand for best viewing angle Keys ON: Turns the power ON and resets the calculator. The power turns off automatically after a few minutes if no key is pressed. The memory is not reset when ON is pressed. OFF: Press to turn OFF the calculator. C/CE: Press to delete a number in the display, Press twice to clear the current calculation. EXP: Exponent key. Press to enter exponents Ex. 40X10 22 Press 4 0 EXP 22 (40 22 ) is displayed +/– Changes the sign of the displayed mantissa and exponents > Backspace Key : Clears the last digit from the display and shifts the other digits to the right. Mode Select Keys INV: Press to perform the function above the keys. MODE: Press to select the calculation mode. Then press 1 – 5 to select the Mode: Press Mode Displayed 1 Decimal DEG 2 Binary BIN 3 Octal OCT 4 Hexadecimal HEX 5 Statistical SD DEG Display Mode Keys Display Mode Keys FLO – SCI – ENG Press to select the display mode. FLOATING: Floating Point Ex. 123456 SCI: Scientific Exponential Ex. 1.2345606 ENG: Engineering Exponential Ex. 123.45604 Display Range Floating Point : 10 -9 –> 1010 Scientific: 10 -99 –> 10 100 Engineering Exponential 10 -99 –> 10 100 Mantissa: Less than 100 Decimal Point Press MODE, then press DRG to set in DEG mode. Press INV and press FIX then a number from 0 to 9 to set the number of numbers to the right of the decimal point. Press INV and press FIX then . (decimal point) to reset the Decimal point location. DRG: Degree/Radian/Gradient Mode Key. Press to change the angle units. DRG> : Angle Conversion key. Used with INV key to convert angle values to different units. 200GRAD= 180 degrees = Pi RAD Basic Functions +, –, x, . keys Press keys as written for basic functions. % key Press for percentage calculations, Add-on and discounts. (…) Open/Close parenthesis keys Press for up to 6 levels of parenthesis when performing complex calculations. Up to 15 consecutive open parenthesis may be used at one time. Notes:Open and close parenthesis must be used together, If only one is used, the calculation will be incorrect. Fractions Accepts fractions and calculates with both mixed and improper fractions. Answers are given in mixed fractions. ab/c Fraction key: Press to enter fractions as shown: Improper fractions A/B: Numerator ab/c Denominator Ex. 6 ab/c 7 = 6/7 <<6_| 7>> is displayed Up to 6 digits may be used for the numerator, 3 digits for the denominator. Mixed Fractions Enter: Integer ab/c Numerator ab/c Denominator Ex. 4 ab/c 6 ab/c...
