f2i : convert float to integer : index : visitInsn()

Description

Pops a single precision float off of the stack, casts it to a 32-bit int, and pushes the int value back onto the stack.

Rounding is done using IEEE 754 round-to-nearest mode. The fractional part is lost by rounding towards zero, so (int)-3.14 becomes -3.

If the original float value is NaN, the result is 0. If the value is too large to be represented as an integer, or if it is positive infinity, the result is the largest possible integer 0x7FFFFFFF. If the value is too small (i.e. a negative value of large magnitude, or negative infinity) then the result is the most negative integer 0x80000000.
