f2d : convert float to double : index : visitInsn()

Description

Pops a single precision float off of the stack, casts it to a double, and pushes the double-precision floating point number back onto the stack. This conversion is done in accordance with IEEE 754 specifications. Note that nothing is lost in this conversion. If the original value is NaN, the result will be NaN. Similarly, if the original value is an infinity, the result will be the same infinity.
