- The round function returns the number that is closest to the argument and that is an integer. If there are two such numbers, then the one that is closest to positive infinity is returned. If the argument is NaN, then NaN is returned. If the argument is positive infinity, then positive infinity is returned. If the argument is negative infinity, then negative infinity is returned. If the argument is positive zero, then positive zero is returned. If the argument is negative zero, then negative zero is returned. If the argument is less than zero, but greater than or equal to -0.5, then negative zero is returned. - -

NOTE

- For these last two cases, the result of calling the round function is not the same as the result of adding 0.5 and then calling the floor function.

- - - fn:number() -
- The number function converts its argument to a number as follows: -
    -
  • a string that consists of optional whitespace followed by an optional minus sign followed by a Number followed by whitespace is converted to the IEEE 754 number that is nearest (according to the IEEE 754 round-to-nearest rule) to the mathematical value represented by the string; any other string is converted to NaN
    • -
  • boolean true is converted to 1; boolean false is converted to 0
    • -
  • a node-set is first converted to a string as if by a call to the string function and then converted in the same way as a string argument
    • -
  • an object of a type other than the four basic types is converted to a number in a way that is dependent on that type
