each function.
|remainder|remainder(x, y) returns the remainder operation on two arguments as
prescribed by the IEEE 754 standard|
|rint|rint(x) returns value that is closest in value to x and is equal to a
mathematical integer|
|round|round(x, y) returns the value of the x rounded to the y decimal places.
While x can be an integer or floating-point number, y must be an integer. The
type of the return value is specified by that of x. y defaults to 0 if omitted.
When y is negative, x is rounded on the left side of the y decimal points. If x
is `NaN`, x returns 0. If x is infinity, x will be converted to the nearest
finite double. |
+|safe_divide|safe_divide(x,y) returns the division of x by y if y is not equal
to 0, returns 0 otherwise|
Review comment:
it's better to put this new function along with the 'div' function above.
