Table 2-14 One-number functions

KeysDescription

§

Divide a number by 100.

 

 

 

\}

Rounds x to the number specified by the display format.

 

 

 

\b

Calculates 1/x.

 

 

 

\B

Calculates the square root of x.

 

 

 

\2

Calculates the square of x.

 

 

 

\K

Calculates natural exponent to the power of x.

 

 

 

\H

Calculates natural log.

 

 

 

\E

Calculates factorial of n (where -253 < n < 253). The Gamma function is

used to calculate n! for non-integers or negative numbers.

 

 

]

Calculates sine, cosine, or tangent.

 

c, R, or C

 

 

 

]o

Calculates inverse sine, cosine, or tangent.

 

c, R, or C

 

 

 

]r

Calculates hyperbolic sine, cosine, or tangent.

 

c, R, or C

 

 

 

]ro

Calculates inverse hyperbolic sine, cosine, or tangent.

c, R, or C

 

 

 

]F

Calculates a cumulative normal probability given a Z-value.

 

 

 

]oF

Calculates a Z-value given a cumulative normal probability.

The random function]6, and Pi \;are special operators. They insert values for Pi, or a random number in the range 0 < x <1, into calculations.
