Syntax

_N

Format a floating-point number.


    
    
    
_N(num)


    
    
    
_N(num, precision)

Examples

For example, _N(3.1415, 2) keeps 3.1415 to two decimal places, removes the remaining digits, and the function returns 3.14.


    javascript
    
    
function main(){
    var i = 3.1415
    Log(i)
    var ii = _N(i, 2)
    Log(ii)
}


    python
    
    
def main():
    i = 3.1415
    Log(i)
    ii = _N(i, 2)
    Log(ii)


    rust
    
    
fn main() {
    let i = 3.1415;
    Log!(i);
    let ii = _N(i, 2);
    Log!(ii);
}

If you need to set the N digits to the left of the decimal point all to 0, you can write it like this.


    javascript
    
    
function main(){
    var i = 1300
    Log(i)
    var ii = _N(i, -3)
    // Check the log and you will see it is 1000
    Log(ii)
}


    python
    
    
def main():
    i = 1300
    Log(i)
    ii = _N(i, -3)
    Log(ii)


    rust
    
    
fn main() {
    let i = 1300;
    Log!(i);
    let ii = _N(i, -3);
    // Check the log and you will see it is 1000
    Log!(ii);
}
