Stack ..., value => ..., result.word1, result.word2
Pops an int off the operand stack, casts it into a double precision floating point number, and pushes the two-word double precision result back onto the stack. This conversion is exact, since doubles have enough precision to represent all int values.
The value on the top of the operand stack must be of type int
. It
is popped from the operand stack and converted to a double
result. The
result is pushed onto the operand stack.
The i2d instruction performs a widening primitive conversion . Because all
values of type int
are exactly representable by type double
, the
conversion is exact.
