Javascript division floor.

When the first operand is a negative value the return value will always be negative and vice versa for positive values. Because of this in javascript 5 will not return 10. If you imagine a room where 3 is on the ceiling and 2 is on the floor. It will return 6.

Towards the lesser value. Java math class provides useful methods for performing the math s operations like exponential logarithm roots and trigonometric equations too. Math floor x parameters x a number. It takes one argument which is a number.

Arithmetic operators are fully described in the js arithmetic chapter. Floor division means the will always take the floor or the lower number. Truncating numbers in javascript math trunc simply removes all the fractional digits. The division operator produces the quotient of its operands where the left operand is the dividend and the right operand is the divisor.

Division modulus division remainder increment decrement. If the passed argument is an integer the value will not be rounded. This tutorial teaches java math class with examples. This operator returns the remainder left over when one operand is divided by a second operand.

2 5 would fit in the middle. If the argument is a positive number it behaves exactly the same as math floor. For negative numbers it does the same job as math ceil. The floor method rounds a number downwards to the nearest integer and returns the result.

Assignment operators assign values to javascript variables. Because floor is a static method of math you always use it as math floor rather than as a method of a math object you created math is not a constructor. It is the value which is to be tested for math floor.
