Floating point constants
WebOct 30, 2024 · Only a very small set of floating point constants can be used with fmov because the constant is encoded as an 8 bit immediate in the instruction. Specifically, it must be representable as ± n /16×2 r where n is an integer in the range 16 ≤ n ≤ 31 and r is an integer in the range of −3 ≤ n ≤ 4. WebFloating-point constants. A floating-point constant specifies a floating-point number as two numbers separated by an E. The first number may include a sign and a decimal point; the second number may include a sign but not a decimal point. The data type of a floating-point constant is double-precision.
