f32.floor
Pops a f32 value off the stack, works out the floor value, and then pushes the result back on to the stack. This rounds down the value to the previous whole number and removes any decimal parts. For example, 1.23 is rounded down to 1.0. For negative numbers it seems like it is rounded up, but it is just taking the negative value into account, so that -1.23 does not change to -1.00, but is changed to -2.0.
