# Dataplot: Elementary Functions

Introduction The following tables list the available elementary functions in Dataplot. For convenience, these functions are divided into real and complex functions.

Available Real Elementary Functions
 ABS(X) absolute value CEIL(X) ceiling function DECOCT(X) decimal-to-octal conversion DIM(X,Y) positive difference (i.e., x-min(x,y)) FLOOR(X) floor function (STEP is a synonym) FRACT(X) fractional portion of a real number GCD(X1,X2) greatest common divisor function HEAVE(X,C) heavside function (=1 if X >= C, 0 otherwise) IND(X,Y) indicator function (=> 1 if x=y, else 0) INT(X) integer portion MAX(X,Y) maximum of two numbers MIN(X,Y) minimum of two numbers MOD(X,Y) modulo (i.e., the remainder of x/y) MSD(X) most significant digit OCTDEC(X) octal-to-decimal conversion ROUND(X) round to the closest integer SIGN(X) sign of a number (=> +1 or -1) SQRT(X) square root

Available Complex Elementary Functions
 CABS(XR,XC) absolute value of a complex number CEXP(XR,XC) real component of the exponential of a complex numbers CEXPI(XR,XC) complex component of the exponential of a complex numbers CSQRT(XR,XC) real component of the square root of a complex number CSQRTI(XR,XC) complex component of the square root of a complex number
