ARITHMETIC FUNCTIONS ABS (X) This gives the absolute (positive) value of the argument. So ABS (-7)=7. Example: PRINT ABS (7-2*4) 1 press ENTER SGN (X) This function will give the value of +1 if X is positive, 0 if X is zero, and -1 if X is negative. So SGN(4.3)=1; SGN(0)=0; SGN(-276)=-1 Example: A=6 PRINT SGN (A); SGN (A-A) 1 0 press ENTER press ENTER INT (X) This converts numbers which are not whole into the largest whole number below the argument. So INT (5.9)=5; also INT (-5.9)=-6. Note that with negative arguments, the absolute value of the result returned by INT will be greater than that of the number. Example: PRINT INT (-6.7) -7 press ENTER RND (X) This will produce a random number between 1 and X if X is a positive number. 52

ARITHMETIC FUNCTIONS
ABS (X)
This gives the absolute (positive) value of the argument.
So ABS (-7)=7.
Example:
PRINT ABS (7-2*4)
press
ENTER
1
SGN (X)
This function will give the value of +1 if X is positive, 0 if X is zero, and -1 if X is negative.
So SGN(4.3)=1; SGN(0)=0; SGN(-276)=-1
Example:
A=6
press
ENTER
PRINT SGN (A); SGN (A-A)
press
ENTER
1
0
INT (X)
This converts numbers which are not whole into the largest whole number below the
argument.
So
INT
(5.9)=5; also
INT
(-5.9)=-6.
Note that with negative arguments, the
absolute value of the result returned by
INT
will be greater than that of the number.
Example:
PRINT INT (-6.7)
press
ENTER
-7
RND (X)
This will produce a random number between 1 and X if X is a positive number.
