A LIST OF NUMERIC FUNCTIONS
Function
ABS (X)
Returns the absolute (positive)Value of X
SGN (X)
Returns the sign of the argument
X negative returns - 1
X positive returns + 1
X zero returns 0
SQR (X) Returns the square root of X. X cannot be negative.
LOG (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.
EXP (X) Gives you the value e - i.e., the natural antilogarithm
of X.
INT (X) Gives the greatest integer which is less than or equal
to X.
RND (X)
Gives a random whole number between 1 and X. If
X equals zero, RND (X) returns a random number
between O and 1. X cannot be negative.
SIN (X) The argument of the trigonometrical functions is taken
COS (X)
to be in radians (1 radian=360/21t = 57.296 degrees) .
TAN (X) The range of X is -999
< (X) <
999.
ATN (X) This gives the result of ARC TANGENT in radians.
ARITHMETIC FUNCTIONS
ABS (X)
This gives the absolute (positive) value of the argument. So ABS (-7) = 7.
Example:
PRINT ABS (7-2* 4)

ENTER
