Buttons The buttons that have a small black triangle in the lower right corner of them have additional related functions. Right click on a button to see its additional functions. The additional functions are listed below with the main entry. Alt Switches between button palettes. See below Base Set Base - Sets the current base Convert Base - Converts from the current base to another base without changing the current base Help with Bases - Brings up the bases help file Cons Display a list of constants that can be added to the expression Conv Display a list of conversions that can be added to the expression Clear Left click peforms the character option

Adds a decimal to the expression , Adds a comma to the expression for use with functions that take multiple arguments Enter Tells the calculator to compute the expression Mod Performs a modulus operation Floor Returns the greatest integer less than the argument Ceil Returns the lowest integer greater than the argument fib Returns the nth Fibonacci number % Returns a percentage (ie. 1/100) Min Returns the minimum of two values Max Returns the maximum of two values gcd Returns the greatest common divisor of two values lcm Returns the least common multiple of two values abs Returns the absolute value of a number fPart Returns the fractional piece of a number iPart Returns the integer piece of a number round rounds a number to the nearest integer != Tests if 2 values are not equal == Tests if 2 values are equal > Tests if the first value is greater than the second value < Tests if the first value is less than the second value >= Tests if the first value is greater than or equal to the second value <= Tests if the first value is less than or equal to the second value n! Returns the factorial of a number nCr Returns the number of combinations of n and r nPr Returns the number of permutations of n and r frand Returns floating point random number between the two arguments irand Returns random integer between the two arguments mean Returns the arithmetic mean (average) of a list of numbers. Ex. mean( 90 : 95 : 88 : 92.5 : 86.5) = 90.4 med Returns the arithmetic median (middle) of a list of numbers. Ex. median( 90 : 95 : 88 : 92.5 : 86.5) = 90 mode Returns the arithmetic mode (number that occurs most often) of a list of numbers. Ex. mode( 90 : 95 : 88 : 92.5 : 86.5) = 90 stdev Returns the standard deviation of a list of numbers. Ex. stdev( 90 : 95 : 88 : 92.5 : 86.5) = 3.056 var Returns the variance of a list of numbers. Ex. variance( 90 : 95 : 88 : 92.5 : 86.5) = 9.339 A Enter the hex digit 'A' B Enter the hex digit 'B' C Enter the hex digit 'C' D Enter the hex digit 'D' E Enter the hex digit 'E' F Enter the hex digit 'F' |
