Structure - Math
The FASIN operator calculates the fl oating point arc sine of a value. FASIN returns the angle in
radians given the ratio of the length of the side opposite the angle and the length of the hypotenuse in
a right triangle.
mysin fcon 1.0
myangle var fl oat
myangle = FASIN mysin ;myfl oat equals PI/2
serout s_out,i9600,[“myangle = “,real myangle,13]
The FACOS operator calculates the fl oating point arc cosine of a value. FACOS returns the angle in
radians given the ratio of the length of the side adjacent the angle and the length of the hypotenuse in
a right triangle.
mycos fcon 0.0
myangle var fl oat
myangle = FACOS mycos ;myfl oat equals 0
serout s_out,i9600,[“myangle = “,real myangle,13]
The FATAN operator calculates the fl oating point arc tangent of a value. FATAN returns the angle in
radians given the ratio of the length of the side opposite the angle and the length of the side adjacent
to the angle in a right triangle.
mytan fcon 1.0
myangle var fl oat
myangle = FATAN mytan ; myfl oat equals PI/4
serout s_out,i9600,[“myangle = “,real myangle,13]
The FLN operator calculates the fl oating point natural log of a value. The natural log is used to
calculate the time it takes for compound growth to reach the specifi ed amount. For example FLN
20.08 will equal approximately 3. This means it takes 3 growth cycles (the amount of time it takes to
grow 100%) to reach 20.08 times the original amount.
