A simple example code converts a given number into number value format with a comma and two decimal points. This turns a number1234.567in to1,234.567. <!DOCTYPE html> var n = 1234.567; var val = Math.round(Number(n) *100) / 100; var parts = val.toString().split("."); var ...
Then the replacement expression inserts a comma at that position. It also takes care of the decimal places by splitting the string before applying the regex expression on the part before the decimal. constnumb=213231221;functionseparator(numb){varstr=numb.toLocaleString().split('.');str[0]=str...
Use toPrecision when you're setting the overall precision. Here, it matters how large the number is before and after the decimal point. This is more useful for mathematical purposes than for formatting. // Example: toPrecision(4) when the number has 7 digits (3 before, 4 after) // It w...
function numberRepresentation(decimal, binary, hexadecimal) { this.decimal = decimal; this.binary = binary; this.hexadecimal = hexadecimal; } numbers =[] for (var i=0;i<=16;i++) { numbers.push( new numberRepresentation( i, i.toString(2), i.toString(16).toUpperCase() ) ); } console...
