How can I check if a number's decimal value is higher than .5 in JavaScript?
For example, I need to know if a number's decimal point is between .5 (higher) and .9 (equal or lower).
Some example numbers: 0.6, 2.7, 4.9.

JavaScript Code:function number_test(n) { var result = (n - Math. floor(n)) !== 0; if (result) return 'Number has a decimal place. '; else return 'It is a whole number.
The decimal number with the greater digit in the tenths place is greater. For example, 9.85 is greater than 9.65. If the digits in the tenths place are equal, compare the digits in the hundredths place. The decimal number with the greater digit in the hundredths place is greater.
To limit the number of digits up to 2 places after the decimal, the toFixed() method is used. The toFixed() method rounds up the floating-point number up to 2 places after the decimal.
The greater a decimal is, the closer it is to one whole. The smaller a decimal is the farther it is from one whole. The first thing you need to look at is the digit number in each decimal. These each have two digits in them, so you can compare them right away.
var num = 5.7;
if((num % 1) > 0.5)
console.write("remainder is greater than 0.5");
