TMtxVec.Trunc Methods

Summary

Rounds a real number towards zero.

Declaration

Function Trunc(Src: TMtxVec; SrcIndex, Index, Len: integer): TMtxVec;

Description

Truncate Src object elements [SrcIndex]..[SrcIndex+Len-1] and store the results to calling object elemenents [Index]..[Index+Len-1]. Size and Complex property of calling object must be set explicitly to match those of Src object. An exception is raised if array borders are overrun/underrun.

Declaration

Function Trunc(var Dst: TIntegerArray): TMtxVec;

Description

Truncate all calling object elements and store the result in the Dst integer array. Length of the array is automatically adjusted. If the calling object is Complex, the length of the Dst array is equal to 2*Length.

Declaration

Function Trunc: TMtxVec;

Description

Rounds all calling object elements towards zero to an integer and stores the result in the calling object again as floating point numbers.
