f64.nearest

Pops a

`f64`

value off the stack, works out the nearest value, and then
pushes the result back on to the stack. This rounds the value to the nearest whole number
and removes any decimal parts. For example, 1.23 is rounded to 1.0, and 1.63 is rounded to 2.0.
Anything 0.5 and below is rounded down and everything above 0.5 is rounded up.

f64 | The value to round. |

f64 | The result of rounding the value to the nearest whole number. |

;; Push the f64 value 1.23 onto the stack f64.const 1.23 ;; Pop the f64 value off the stack, round to the nearest value and ;; push the result back onto the stack f64.nearest ;; The stack contains an f64 value of 1.0

;; Push the f64 value 2.65 onto the stack f64.const 2.65 ;; Pop the f64 value off the stack, round to the nearest value and ;; push the result back onto the stack f64.nearest ;; The stack contains an f64 value of 3.0

;; Push the f64 value -2.65 onto the stack f64.const -2.65 ;; Pop the f64 value off the stack, round to the nearest value and ;; push the result back onto the stack f64.nearest ;; The stack contains an f64 value of -3.0

;; Push the f64 value 3.5 onto the stack f64.const 3.5 ;; Pop the f64 value off the stack, round to the nearest value and ;; push the result back onto the stack f64.nearest ;; The stack contains an f64 value of 3.0
