jfloat: Wrap numeric vector as flat Java parameter
Description
.jfloat
marks a numberic vector as an object that can be used as parameter to Java calls that require float
parameters.Value
- Returns a numeric vector fo the class
jfloat
that can be used as parameter to Java calls that require float
parameters.
Details
R has no native float
type. Numeric vectors are stored as double
s, hence there is no native way to pass float numbers to Java methods. The .jfloat
call marks a numeric vector as having the Java type float
by wrapping it in the jfloat
class. The class is still a subclass of numeric
, therefore all regular R operations are unaffected by this.
