C. Built-in Functions 173
string form “YYYYMMDD”. Here YYYY is the year, MM is the month number, and DD is
the day number. If your computer cannot tell the date, then DATE$ returns “00000000”.
DEG Function
DEG(numeric-expression)
Returns the number of degrees in numeric-expression radians. This function is not affected
by the current OPTION ANGLE.
DET Function
DET (numarr)
DET
Returns the value of the determinant for the square numeric matrix named as its argument.
DOT Function
DOT(arrayarg, arrayarg)
DOT computes and returns the dot product of two arrays, which must be one-dimensional,
numeric, and have the same number of elements. (The subscript ranges need not be the
same, however.) If both arrays have no elements, then DOT returns 0.
EPS Function
EPS(numeric-expression)
EPS(x) returns the smallest positive number that can “make a difference” when added to or
subtracted from x.
EXLINE Function
EXLINE
EXLINE returns the line number in your program where the most recent error occurred. If
your program does not have line numbers, EXLINE returns the ordinal number of the line
in the file.
EXLINE$ Function
EXLINE$
EXLINE$ returns a string that gives the location in your program where the most recent
error occurred. It gives the number of the line and the routine in which the error occurred.
If the error occurred deeply in nested subroutine calls, EXLINE$ returns the geneology of
the error; i.e., it includes the names of the intervening subroutines and the line numbers of
the CALL statements.
