![]() ![]() If you’d like to see it in action, here’s a demo. When comparing two strings, '2' will be greater than '12', because (alphabetically) 1 is less than 2. ![]() A non-numeric string converts to NaN which is always false. If the number has more than three digits, it should be displayed differently. To use something other than a dollar sign in the currency, simply replace the ‘$’ in the return line with your currency sign. When comparing a string with a number, JavaScript will convert the string to a number when doing the comparison. The number presented as monetary value is readable and eye-catching.If you are starting with a number that uses a comma to denote a decimal, you’d also need to change the dollars and cents variables to have “.split(‘,’)” instead of “.split(‘.’)”. If you use a comma instead of a period between dollars and cents, change “dollars + ‘.'” in the return line to read “dollars + ‘,'” instead.If your currency of choice uses periods instead of commas as a thousands-place divider, change ‘$1,’ in the replace function to be ‘$1.’ Instead.reverse() puts the numbers back in the proper order:Īfter that, all we do is return our manipulated number with a dollar sign out front and a decimal point between dollars and cents (and I’m using slice to only return the first two digits in the cents string). split(”) converts our newly comma’d string to an array again: function toUSD(number) (?!$))/g, ‘$1,’) is a complicated (for me) regular expression that basically says “add a comma to the end of every group of three numbers, unless it is the last group of three numbers (to avoid trailing commas)”: The JavaScriptįirst the script, then the explanation. But there’s also the problem of whole-dollar and multiple-of-ten-cent amounts: I would have “500” when the user would expect “500.00”, or “250.2” when the user would expect “250.20”. ![]() The numbers never included commas, of course. Note: The decimal data type can store larger numbers than the double data type, so it’s always advisable to use the decimal data type when you are uncertain.I wrote this script because I had to display dollar amounts in a “friendly” format in several places on a website, but I wasn’t being handed friendly numbers by the server. You can use the Immediate Window to see how the value would be processed if not converted to a double or decimal data type: Debug.Print "13.57" + "13.4" The following code would convert a string to a decimal data type: MsgBox CDec("13.57") + CDec("13.4") The following code would convert a string to a double data type: MsgBox CDbl("9.1819") You can use the CDbl or CDec function to convert a string to a decimal. Usually, the text will be stored as a variable and this variable will need to be converted to a number data type as shown in the code below: Sub Using_Variables() You can use the Immediate Window to see how the value would be processed if not converted to an integer: Debug.Print "13.5" + "13.5" So it’s always better to use a long data type instead of an integer. In modern programming, there’s no reason not to use the long data type since memory is no longer an issue. In the past, the distinction was required because of memory constraints. The Long Data type is the same as an integer data type except larger numbers are allowed. This means it can represent fractional values, but there are some limits to the stored number's magnitude and precision. ![]() Note: You can use the CInt or CLng function to convert a string to an integer or long (respectively) data types. The JavaScript Number type is a double-precision 64-bit binary format IEEE 754 value, like double in Java or C. The following code uses the CLng function to convert a string to an integer: MsgBox CLng("13.5") The following code will convert a string to an integer: MsgBox CInt("7.55") 5 the function will round down, if the fraction is greater than or equal to. You can use the CInt or CLng function to convert a string to an integer. In this tutorial, we are going to go over the functions that you need to use to convert a string to an integer, long, double, decimal or currency data type ( Click here to learn about converting numbers to strings) Convert String to Integer You may be required to convert numbers stored as text to actual numbers in your VBA code. +str - (E.g. ![]()
