Can you help me with a decimal number display issue I am having?
<nested:text property="product.price" maxlength="5" onclick="javascript:validatePriceValue(this);"/>
| number | displayed as |
|---|---|
| 44 | 44.00 |
I want to use Javascript to display only 44 without the .00
Any suggestions on how to achieve this?
Here are several methods for converting a float to an int:
let x = parseInt("1000.0", 10); // This function disregards anything after the decimal point. While providing a radix of 10 is not strictly necessary, it is recommended to ensure accurate interpretation as a decimal number.
let x = Math.floor("1000.01"); // Round down to the nearest integer -> 1000
let x = Math.ceil("1000.01"); // Round up to the nearest integer -> 1001
let x = Math.round("1000.01"); // Round to the closest whole number -> 1000
Say you have a number stored in a variable called num as a string, like so:
num = "78.00";
To extract the whole number without decimals, simply use the parseInt function:
newNum = parseInt(num);
It's possible that there is a rounding issue occurring. Without seeing the code and specific values, it's difficult to diagnose.
One potential solution, although not elegant, is to try the following workaround:
// value
// pseudo-down-casting to an integer in JavaScript
w = parseInt("" + v, 10);
Give this a shot:
let num = 55.00;
let intNum = parseInt(num);

To achieve the desired result of removing the decimal portion, you have a few options in JavaScript. You could utilize the Math.floor() function to round down, Math.ceil() to round up, or Math.round() to round to the nearest integer.
If truncating the decimal is all you're after, consider using bitwise operators such as |0 which treats the operand as a signed 32bit integer.
It's also worth noting the potential inaccuracies that can arise due to floating point arithmetic when working with decimals.
