String interpolation does not consist to C version

[kbkpbot]

Describe the bug

String interpolation of float precision should consist to it's C version.

Reproduction Steps

A format.v

module main

fn main() {
        x := 1.234
        println('[${x:1.15g}]')
}

This will give a result of :

[1.234000000000000]

But a C version format.c

#include <stdio.h>

void main() {
        double a = 1.234;
        printf("[%1.15g]\n",a);
}

will generate result:

[1.234]

Expected Behavior

V version will generate same result to it's C version:

[1.234]

Current Behavior

[1.234000000000000]
