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 `expr` evaluates to either `NaN`, `expr` will be
converted to 0. If `expr` is infinity, `expr` will be converted to the nearest
finite double. |
