FPU.TAN(); A = tan(A) radians

example 1:

#include<LCD4_128.h>
#include<FPU_128.h>

void main()
{
   float x;

   Init_Fpu();    // Initialize FPU

   x = TAN(3.333);

   FPU.FWRITEA(5,x);

}

example 2:

#include<LCD4_128.h>
#include<FPU_128.h>

float get(float sqrt)
{
   return sqrt*6.323;
}

void main()
{
   float x;

   Init_Fpu();    // Initialize FPU
   Lcd_init();     // Initialize LCD

   x = get(TAN(3.333)) / 7.2;

   LCD.PRINT(x); // will print -0.8621554

}

example 3:

#include<LCD4_128.h>
#include<FPU_128.h>

void main()
{
   float x;

   Init_Fpu();    // Initialize FPU
   Lcd_init();     // Initialize LCD

   FPU.FWRITEA(1,3.33);
   FPU.TAN();   // A = tan(A) radians
