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 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
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=360/2π = 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.
Example:
PRINT ABS (7-2*4) press Enter
