truncated - multiple declarations

Function truncated

Returns a point with each fractional coordinate part removed.

Point2!T truncated(T)(
  Point2!T value
) pure nothrow @nogc @property @safe
if (isFloatingPoint!T);

This operation is available only for floating-point geometry. Finite coordinates are rounded toward zero and the original scalar type is retained. NaN and infinities remain non-finite floating-point values; signed zero is preserved.

No allocation is performed.

Complexity

O(1) time and O(1) auxiliary space.

Function truncated

Returns a vector with each fractional component removed.

Example

Example removing fractional parts toward zero. 

import geo;

const point =
    Point2!double(
        1.75,
        -2.25
    );

const vector =
    Vector2!double(
        -1.25,
        2.75
    );

assert(
    point.truncated ==
    Point2!double(
        1.0,
        -2.0
    )
);

assert(
    vector.truncated ==
    Vector2!double(
        -1.0,
        2.0
    )
);
