[BUG] PCA casts double values that are too large to be represented as an integer.

Environment

Debian Trixie

Describe the bug

PCA is casting double values that cannot be represented as an integer.

When running the unit tests with FPE enabled:

[----------] 1 test from TestPCA
[ RUN      ] TestPCA.testPCA

Thread 1 "vdb_test" received signal SIGFPE, Arithmetic exception.

To Reproduce

Run TestPCA with FPE enabled

Expected behavior

No FP exception.
