Struct FixedPoint32

Namespace
Core.Data
Assembly
Core.dll

32-bit fixed-point number for deterministic calculations Format: 16.16 (16 integer bits, 16 fractional bits) Range: -32,768 to 32,767 with ~0.00002 precision

Use when memory is constrained or smaller range is acceptable. For most simulation math, prefer FixedPoint64 for its larger range.
