A LIST OF NUMERIC FUNCTIONS
Function
What it does
ABS (X)
Returns the absolute (postive) value of X
SGN (X)
Returns the sign of the argument
X negative returns -1
X postive r 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
x
- 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 0 and 1. X cannot be
negative.
SIN (X)
The argument of the trigonometry functions is taken to be in radians
COS (X)
(1 radian=360/2
π
= 57.296 degrees). The range of X is -999 < (X)
TAN (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.
