vec.trunc

vec.trunc(
   vector as vec.vector,
   [n as Number?]
) as vec.vector

Returns a new vector which is a copy of the input vector with each element truncated to a specific number of digits.

Parameters
vector	The input vector to truncate.
n	The numbers of decimal places to truncate to. The default is 0. Negative values cause that many digits to the left of the decimal point to be truncated.

  const vec1 = vec.vector([1.234,2.654])
  vec.trunc(vec1, 2)

  => "[ 1.23, 2.65 ]"
