The signif function rounds a numeric input to a specified number of digits.

Floor vs truncate.

This kind of rounding is sometimes called rounding toward negative infinity. This corrects the bias towards larger numbers when performing a large number of calculations. If d is 0 then the decimal point is removed. The truncate function is used to return the value of x truncated to d number of decimal places.

If the number is exactly midway between two integers then it. If d is negative then d number of values in the integer part of the value is truncated. The following example illustrates the math floor double method and contrasts it with the ceiling double method. Floor ceil and trunc always return an integral value while round returns an integral value if called with one argument.

The trunc function truncates i e. For completeness math round rounds to the nearest integer. The behavior of this method follows ieee standard 754 section 4. Double values 7 03 7 64 0 12 0 12.
