Enumeration Type Documentation

enum FpuPrecision

Represents different floating-point precision modes. Enumerator: FPU_PREC_SINGLE  fpu operates in single precision (32-bit, 24-bit significand) FPU_PREC_DOUBLE  fpu operates in double precision (64-bit, 53-bit significand) FPU_PREC_EXTENDED  default: fpu operates in extended precision (80-bit, 64-bit significand) Definition at line 50 of file fpu.H.

enum FpuRoundingMode

Represents different floating-point rounding modes. Enumerator: FPU_ROUND_NEAR  fpu rounds to nearest value FPU_ROUND_DOWN  fpu rounds toward -inf FPU_ROUND_UP  fpu rounds toward +inf FPU_ROUND_ZERO  fpu rounds toward zero Definition at line 76 of file fpu.H.
