Functions

• dadd
  Calculates a + b
• datan2
  Computes the arc tangent of y/x using the signs of arguments to determine the correct quadrant
• dcmp
  Compares two floating point numbers, returning: • 0 if a == b • -1 if a < b • 1 if a > b
• dcos
  Calculates the cosine of angle. The value of angle is in radians, and must be in the range -1024 to 1024
• ddiv
  Calculates a / b
• dexp
  Calculates the exponential value of v, i.e. e ** v
• dln
  Calculates the natural logarithm of v. If v <= 0 return -Infinity
• dmul
  Calculates a * b
• double_to_fix
  Converts an f64 to an signed fixed point integer representation where n specifies the position of the binary point in the resulting fixed point representation, e.g. f(0.5f, 16) == 0x8000. This method rounds towards -Infinity, and clamps the resulting integer to lie within the range 0x00000000 to 0xFFFFFFFF
• double_to_fix64
  Converts an f64 to a signed fixed point 64-bit integer representation where n specifies the position of the binary point in the resulting fixed point representation - e.g. f(0.5f, 16) == 0x8000. This method rounds towards -Infinity, and clamps the resulting integer to lie within the range -0x8000000000000000 to 0x7FFFFFFFFFFFFFFF
• double_to_float
  Converts an f64 to an f32
• double_to_int
  Converts an f64 to a signed integer, rounding towards -Infinity, and clamping the result to lie within the range -0x80000000 to 0x7FFFFFFF
• double_to_int64
  Convert an f64 to a signed 64-bit integer, rounding towards -Infinity, and clamping the result to lie within the range -0x8000000000000000 to 0x7FFFFFFFFFFFFFFF
• double_to_ufix
  Converts an f64 to an unsigned fixed point integer representation where n specifies the position of the binary point in the resulting fixed point representation, e.g. f(0.5f, 16) == 0x8000. This method rounds towards -Infinity, and clamps the resulting integer to lie within the range 0x00000000 to 0xFFFFFFFF
• double_to_ufix64
  Converts an f64 to an unsigned fixed point 64-bit integer representation where n specifies the position of the binary point in the resulting fixed point representation, e.g. f(0.5f, 16) == 0x8000. This method rounds towards -Infinity, and clamps the resulting integer to lie within the range 0x0000000000000000 to 0xFFFFFFFFFFFFFFFF
• double_to_uint
  Converts an f64 to an unsigned integer, rounding towards -Infinity, and clamping the result to lie within the range 0x00000000 to 0xFFFFFFFF
• double_to_uint64
  Converts an f64 to an unsigned 64-bit integer, rounding towards -Infinity, and clamping the result to lie within the range 0x0000000000000000 to 0xFFFFFFFFFFFFFFFF
• dsin
  Calculates the sine of angle. The value of angle is in radians, and must be in the range -1024 to 1024
• dsqrt
  Calculates sqrt(v) (or return -Infinity if v is negative)
• dsub
  Calculates a - b
• dtan
  Calculates the tangent of angle. The value of angle is in radians, and must be in the range -1024 to 1024
• fix64_to_doubl
  Converts a signed fixed point 64-bit integer representation to the nearest double value, rounding to even on tie. n specifies the position of the binary point in fixed point, so f = nearest(v/(2^n))
• fix_to_double
  Converts a signed fixed point integer representation to the nearest double value, rounding to even on tie. n specifies the position of the binary point in fixed point, so f = nearest(v/(2^n))

• int_to_double
  Converts a signed integer to the nearest double value, rounding to even on tie
• ufix64_to_double
  Converts an unsigned fixed point 64-bit integer representation to the nearest double value, rounding to even on tie. n specifies the position of the binary point in fixed point, so f = nearest(v/(2^n))
• ufix_to_double
  Converts an unsigned fixed point integer representation to the nearest double value, rounding to even on tie. n specifies the position of the binary point in fixed point, so f = nearest(v/(2^n))
