Math Utilities

Numeric helpers Verse lacks out of the box: Modulo, ClampInt/Float, SafeDivide, RoundTo, LerpFloat, and a zero-safe vector SafeNormalize.

Original, compile-verified Verse by Bizanator (Biloxi Studios). Clean-room sample you can drop into a UEFN project and adapt.

  # Generic numeric helpers Verse doesn't ship out of the box: integer modulo,
  # clamping, safe division, rounding to N decimals, linear interpolation, and a
  # zero-safe vector normalize. Dependency-free.
  #
  # Teaches: <decides>/<transacts> effects, Int[]/Round[]/Floor[] failable casts,
  # guarding division by zero, and basic vector math.
