-# Requirements Specification(fx_s3132)
-
-## 1. introduction
-### - 1.1 purpose
-- 1.1.1 basic purpose
-  - This product is a kind of calculator that performs various operations related to fixed point number.
-  - For fixed-point arithmetic, c langauge's math library and type conversion are required.
-  - in iteration2, with using shift operation can create a variety of functions that perform differently under different conditions.
-
-### - 1.2 concept
-- 1.1.2 basic concept
-  - To operate several calculation for fixed-point numebr type casting is essential.
-  - Correct type conversion is very important in order to accurately calculate and avoid missing bits.
-- 1.1.3 concept of fixed-point number
-  - ![image](/uploads/0ae109d4300d11722c53531d1a9615ac/image.png)
-    - a. data types in computer langauge always have fixed length 
-    - b. in fixed point decimal point position of specific number should be fixed
-    - c. mean of s3132
-      - s(sign) / 31(interger) / 32(decimal point)
-      - first s bit is used for number's sign (+ or -)
-      - second 31bits are used to represent interger part
-      - third 32bits are used to represent decimal 
-
-## 2. overall description
-### - 2.1 product functions
-- 2.1.1 list of fuctions
-  - 2.1.1.1 iteration 1
-    - a. add
-      ~~~
-      #define fx_add(a, b) ((a)+(b))
-      ~~~
-      - to add two fixed point numbers there is no need to conversion of data type
-      - just add two fixed point numbers and return result
-    - b. sub
-      ~~~
-      #define fx_sub(a, b) ((a)-(b))
-      ~~~
-      - to sub one fixed point number from another fixed point number there is no need to conversion of data type.
-      - just operate function without conversion of data type and return result
-    - c. mul
-      ~~~
-      #define fx_mul(a, b) double_to_fx(fx_to_double (a) * fx_to_double (b))
-      ~~~
-      - to mul two fixed pouint number shoul do type conversion
-      - first convert two fixed point number to double type and do mul operation
-      - second result calculated from first step should be converted to fixed point number(type conversion)
-    - d. div
-      ~~~
-      #define fx_div(a, b) double_to_fx(fx_to_double (a) / fx_to_double (b))
-      ~~~
-      - to div two fixed pouint number shoul do type conversion
-      - first convert two fixed point number to double type and do div operation
-      - second result calculated from first step should be converted to fixed point number(type conversion)
-    - e. fixed -> double
-      ~~~
-      #define fx_to_double(a) (a/P2_2to32)
-      ~~~
-      - to convert fixed point to double should divide fixed point number by 2^32(s31(32)=>decimal part bits)
-    - f. double -> fixed
-      ~~~
-      #define double_to_fx(a) (long long)(a*P2_2to32)
-      ~~~
-      - to convert double to fixed point should multiply double number and 2^32(s31(32)=>decimal part bits)
-    - h. sine
-      ~~~
-      #define fx_sin(a) double_to_fx(sin(fx_to_double(a)))
-      ~~~
-      - to convert fixed point number to sine value there is need to type conversion
-      - first convert fixed number to double
-      - second do sine operation with math library
-      - thrid conver result calculated by second step to double and return result
-    - i. power
-      ~~~
-      #define fx_power(a, b) double_to_fx(pow(fx_to_double(a), fx_to_double(b)))
-      ~~~
-      - to do power operation with fixed point number there is need to type conversion
-      - first convert fixed number to double
-      - second do sqrt operation with math library
-      - thrid conver result calculated by second step to double and return result
-    - j. sqrt
-      ~~~
-      #define fx_sqrt(a) double_to_fx(sqrt(fx_to_double(a)))
-      ~~~
-      - to do sqrt operation with fixed point number there is need to type conversion
-      - first convert fixed number to double
-      - second do sqrt operation with math library
-      - thrid conver result calculated by second step to double and return result
-  - 2.1.1.2 iteration 2
-    - a. mul
-      ~~~
-      ((fa * fb) >> FX32_QNUM ) 
-      ~~~
-      - fuction that multiplies fa and fb and divides it by 2^32
-    - b. mul1
-      ~~~
-      ((fa>>16) * fb)>>16)
-      ~~~
-      - Same as fx32_mul, the same fuction as fa*fb>>32, first multiply fa/2^16 and fb, and divide the remaining 2^16

-      ((((fa)<<16)/(fb))<<16)
-      ~~~
-      - Same as above, it has the same fuction as (fa<<32)/fb. First, fa is multiplied by 2^16 and divided by fb, and then the remaining 2^16 is multiplied
-    - f. div2
-      ~~~
-      ((((fa)<<24)/(fb))<<8)
-      ~~~
-      - same as above, it has the same fuction as (fa<<32)/fb. First, fa is multiplied by 2^24, divided by fb, and then the remaining 2^8 is multiplied.
