f64.trunc

Pops a

`f64`

value off the stack, truncates the value, and then
pushes the result back on to the stack. This removes any decimal parts to leave only the
whole number remaining. It is similar to the `f64.floor`

instruction except it
operates differently will negative numbers. For example, 1.23 becomes 1.0, and -1.23 becomes -1.0,
unlike the floor instruction which would result in -2.0.

f64 | The value to get truncated. |

f64 | The truncated value of the value given. |

;; Push the f64 value 3.142 onto the stack f64.const 3.142 ;; Pop the f64 value off the stack, truncate the value and ;; push the result back onto the stack f64.trunc ;; The stack contains an f64 value of 3.0

;; Push the f64 value -12.34 onto the stack f64.const -12.34 ;; Pop the f64 value off the stack, truncate the value and ;; push the result back onto the stack f64.trunc ;; The stack contains an f64 value of -12.00
