l2d

l2d Stack

Pops a long integer off of the stack, casts it into a double precision floating point number, and pushes the double back onto the stack. Notice that this can cause loss of precision (the significand in a double is 54 bits, compared to 64 bits for the long) though not loss of magnitude (since the range of a double is greater than the range of a long). Rounding is done using the IEEE 754 round-to-nearest mode.
