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).

f32 | The value to make absolute. |

f32 | The absolute value of the value given. This is always the positive version of the value. |

;; Push the f32 value 3.142 onto the stack f32.const 3.142 ;; Pop the f32 value off the stack, workout the absolute value and ;; push the result back onto the stack f32.abs ;; The stack contains an f32 value of 3.142

;; Push the f32 value -2.718 onto the stack f32.const -2.718 ;; Pop the f32 value off the stack, workout the absolute value and ;; push the result back onto the stack f32.abs ;; The stack contains an f32 value of 2.718
