expr
The expression to be converted.
Converts an expression tointeger data type.
Extracts data from an expression and places it in a integer scalar or array.
The expression to be converted.
The expression from which to extract data.offset
The offset, in bytes, from the beginning of expr to where the extraction is to begin. dimi
(optional) The dimensions of the result. May be any scalar expression. Up to eight dimensions may be specified.
A copy of expr converted to integer data type.
If offset is used, FIX does not convert result, but allows fields of data extracted from expr to be treated as integer data. If no dimensions are specified, the result is scalar.
CAUTION: If the values of expr are within the range of a long integer, but outside the range of the integer data type (-32,768 to +32,767), a misleading result occurs, without an accompanying message. For example,FIX(66000)erroneously results in 464.
a = FINDGEN(6) + 0.6
PRINT, a 0.600000 1.60000 2.60000 3.60000 4.60000 5.60000 b = FIX(a)
.
INFO, b
B INT = Array(6)
PRINT, b
0 1 2 3 4 5
c = FIX(b, 4, 2, 2)
INFO, c
C INT = Array(2, 2)
PRINT, c
2 3
4 5
