Type PRINT SQR (9).
The answer is 3.
Example:
Y=9 : X=SQR(Y) : PRINT X
The answer is 3.
In these two examples, 9 is the argument, SQR is the function and 3 is the result.
A LIST OF NUMERIC FUNCTIONS
Function
ABS (X)
SGN (X)
SQR (X)
LOG (X)
EXP (X)
INT (X)
RND (X)
SIN (X)
COS (X)
TAN (X)
ATN (X)
(press ENTER)
What it does
Returns the absolute (positive) Value of X
Returns the sign of the argument
X negative returns - 1
X positive returns + 1
X zero returns 0
Returns the square root of X.
Gives the natural logarithm of X, i.e.,
the logarithm to the base e (=2.71828).
The value of the argument must be greater than zero.
Gives you the value e
of X.
Gives the greatest integer which is less than or
equal to X.
Gives a random whole number between 1 and X.
If X equals zero, RND (X) returns a random number
between 0 and 1.
The argument of the trigonometrical functions
is taken to be in radians (1 radian=360/2π = 57.296 degrees).
The range of X is -999 < (X) < 999.
This gives the result of ARC TANGENT in radians.
press ENTER
X cannot be negative.
x
, i.e., the natural antilogarithm
X cannot be negative.
