NAME
size - number of elements in value
SYNOPSIS
size(x)
TYPES
x any
return integer
DESCRIPTION
For the different types of value x may have, size(x) is defined as follows:
null 0
real number 1
complex number 1
string length of string (not including the trailing \0)
matrix number of elements
list number of members
association number of (elements, value) pairs
object value returned by xx_size(x) if x of type xx
file length of the file in octets
rand state 1
random state 1
config state 1
hash state 1
block number of octets of data it currently holds
octet 1
named block number of octets of data it currently holds
EXAMPLE
; print size(null()), size(3), size(2 - 7i), size("abc")
0 1 1 1
; mat M[2,3]
; print size(M), size(list()), size(list(2,3,4))
6 0 3
; A = assoc()
; A[1] = 3, A[1,2] = 6, A["three"] = 5
; print size(A)
3
; obj point {x,y}
; obj point P = {4,-5}
; define point_size(a) = abs(a.x) + abs(a.y)
; print size(P)
