expr
The expression to be converted, or from which to extract data.
Converts an expression tosingle-precision floating-point data type.
Extracts data from an expression and places it in a single-precision floating-point scalar or array.
The expression to be converted, or from which to extract data.
The expression to be converted, or 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 single-precision floating-point data type.
If offset is used, FLOAT does not convert result, but allows fields of data extracted from expr to be treated as single-precision floating-point data. If no dimensions are specified, the result is scalar.
a = INDGEN(6)
PRINT, a
0 1 2 3 4 5
b = FLOAT(a)
.
INFO, b
B FLOAT = Array(6)
PRINT, b
0.00000 1.00000 2.00000 3.00000 4.00000

c = FLOAT(b, 8, 2, 2)
INFO, c
C FLOAT = Array(2, 2)
PRINT, c
2.00000 3.00000
