Format P1 = ACOS( P2 ) Data Type F
Function Calculates the arccosine of the value of P2 and saves the result to P1.
P1 (I) The result in the range 0 to π. If the value of P2 is less than -1 or greater than 1, the result will be an indefinite by default.
P2 (I/C) The value between -1 to 1 whose arccosine is to be calculated.
Example 1 $U100 = 0 (F) /* Assign 0 to $U100 (and $U101)*/
$U200 = ACOS($U100) (F) /* Write the result 1.570796 of arccosine of 0 to $U200 (and $U201)*/

■ ASIN

Format P1 = ASIN( P2 ) Data Type F
Function Calculates the arcsine of the value of P2 and saves the result to P1.
P1 (I) The result in the range -π/2 to π/2. If the value of P2 is less than -1 or greater than 1, the result will be an indefinite by default.

■ ATAN

Format P1 = ATAN( P2 ) Data Type F
Function Calculates the arctangent of the value of P2 and saves the result to P1.
