Bit Reinterpret Helpers

The Bit Reinterpret Helpers allow scripts to inspect the raw bit-pattern of numeric values by converting them into a uint32.

These functions do not convert or scale values — they reinterpret the raw memory bits of the input

---

uint32 f_to_u32(float f)

Returns the raw 32-bit IEEE-754 representation of a float.

uint32 bits = f_to_u32(1.0f);     // 0x3F800000

---

uint32 u8_to_u32(uint8 v)

Reinterprets a uint8 as a uint32.

uint32 bits = u8_to_u32(255);     // 0x000000FF

---

uint32 u16_to_u32(uint16 v)

Reinterprets the lower 16 bits of a uint16 as a 32-bit integer.

uint32 bits = u16_to_u32(50000);

---

uint32 u64_to_u32(uint64 v)

Returns the lower 32 bits of a 64-bit unsigned integer.

uint32 bits = u64_to_u32(0x1122334455667788);

---

uint32 i8_to_u32(int8 v)

Reinterprets a signed 8-bit integer as a 32-bit unsigned integer.

uint32 bits = i8_to_u32(-5);      // 0xFFFFFFFB

---

uint32 i16_to_u32(int16 v)

Reinterprets a signed 16-bit integer as 32 bits.

uint32 bits = i16_to_u32(-1234);

---

uint32 i32_to_u32(int32 v)

Reinterprets a signed 32-bit integer as an unsigned one without numerical conversion.

uint32 bits = i32_to_u32(-1);     // 0xFFFFFFFF

---

uint32 i64_to_u32(int64 v)

Returns the lower 32 bits of a 64-bit signed integer.

uint32 bits = i64_to_u32(-1);     // 0xFFFFFFFF

---

uint32 d_to_u32(double v)

Returns the first 4 bytes of a 64-bit double (the lower half of the binary representation).

uint32 bits = d_to_u32(3.1415926535);

---

float bits_to_float(uint raw)

Reinterprets a 32-bit unsigned integer as an IEEE-754 float.

float f = bits_to_float(0x3F800000);    // 1.0f

---

double bits_to_double(uint64 raw)

Reinterprets a 64-bit unsigned integer as an IEEE-754 double.

double d = bits_to_double(0x400921FB54442D18);   // 3.141592653589793

---

uint float_to_bits(float value)

Returns the exact 32-bit IEEE-754 bit pattern of a float.

uint bits = float_to_bits(1.0f);        // 0x3F800000

---

uint64 double_to_bits(double value)

Returns the exact 64-bit IEEE-754 bit pattern of a double.

uint64 bits = double_to_bits(3.141592653589793); // 0x400921FB54442D18

---

float u32_to_f(uint raw)

Convenience alias for bits_to_float(raw).

float f = u32_to_f(0xBF800000);         // -1.0f
