Use $asin to calculate the arcsine (in radians) of a number. The value returned by this function has the same number of decimal places as number. The absolute value of the number must be between 0 and 1.
let vAngle[2] = $asin(0.500)
The preceding command sets the second element of array variable vAngle to 0.524.
