f32.abs
Pops a f32 value off the stack, works out the absolute value, and then pushes the result back on to the stack. If the value is positive then that is the value pushed onto the stack. If the value is negative then it is changed into a positive one, for example, -3.142 become 3.142, and 2.718 stays as 2.718 (because it is already positive).
