Using math.div instead of / in scss

Need to rewrite this function using math.div instead of slash. Details mentioned in the URL given below.

    @function px2em($px, $metric: 'em', $base-font-size: 16px) {
      @if unitless($px) {
        @warn "Assuming #{$px} to be in pixels, attempting to convert it into pixels.";
        @return px2em($px * 1px, $metric, $base-font-size);
      } @else if unit($px) == em {
        @return $px;
      }  
      @return #{($px / $base-font-size) + $metric};
    }
    
    // Pixels to rem based on sass-mq
    @function px2rem($px) {
      @if unit($px) == rem {
        @return $px;
      }

      @return px2em($px, 'rem');
    }

@return #{($px / $base-font-size) + $metric};

Here are your functions with the updated syntax. Make sure to keep the @use import at the top of your file.

@use "sass:math";

@function px2em($px, $metric: 'em', $base-font-size: 16px) {
  @if unitless($px) {
    @warn "Assuming #{$px} to be in pixels, attempting to convert it into pixels.";
    @return px2em($px * 1px, $metric, $base-font-size);
  } @else if unit($px) == em {
    @return $px;
  }
  $test: #{math.div($px, $base-font-size) + $metric};
  @return $test;
}

// Pixels to rem based on sass-mq
@function px2rem($px) {
  @if unit($px) == rem {
    @return $px;
  }

  @return px2em($px, 'rem');
}
