4. Function Calculations
k Function Menus
This calculator includes five function menus that give you access to scientific functions not
printed on the key panel.
• The contents of the function menu differ according to the mode you entered from the Main
Menu before you pressed the K key. The following examples show function menus that
appear in the Run-Matrix or Program mode.
u Hyperbolic Calculations (HYPERBL)
• {sinh}/{cosh}/{tanh} ... hyperbolic {sine}/{cosine}/{tangent}
• {sinh –1 }/{cosh
u Probability/Distribution Calculations (PROB)
x!
• { } ... press after inputting a value to obtain the factorial of the value
n r n r
• { P }/{ C } ... {permutation}/{combination}
• {RAND} ... {random number generation}
• {Ran#}/{Int}/{Norm}/{Bin}/{List}/{Samp} ... {random number generation (0 to 1)}/{random
integer generation}/{random number generation in accordance with normal distribution
based on mean
with binomial distribution based on number of trials
generation (0 to 1) and storage of result in ListAns}/{random extraction of list data
elements and storage of result in ListAns}
• {P(}/{Q(}/{R(} ... normal probability {P(
t
• { (} ... {value of normalized variate
u Numeric Calculations (NUMERIC)
• {Abs} ... select this item and input a value to obtain the absolute value of the value
• {Int}/{Frac} ... select the item and input a value to extract the {integer}/{fraction} part.
• {Rnd} ... rounds off the value used for internal calculations to 10 significant digits (to match
the value in the answer memory), or to the number of decimal places (Fix) and number
of significant digits (Sci) specified by you
• {Intg} ... select this item and input a value to obtain the largest integer that is not greater
than the value
• {RndFix} ... rounds off the value used for internal calculations to specified digits (0 to 9) (see
page 2-2)
• {GCD} ... {greatest common divisor for two values}
• {LCM} ... {least common multiple for two values}
• {MOD} ... {remainder of division (remainder output when
• {MOD_Exp} ... {remainder when division is performed on a power value (remainder output
