The nearest integer value not greater than x in magnitude.

If x is integer or boolean, then trunc() will return this value converted to float64. If x is floating-point, then trunc(x) acts as floor(x) for positive values of x, and as ceil(x) for negative values of x. This rounding mode is known as rounding towards zero.
