ASIN(nExpression) |
Parameters
- nExpression
- Specifies the numeric expression whose arc sine ASIN( ) returns. The value of nExpression can range from +1 through –1, and the value ASIN( ) returns can range from –pi/2 through +pi/2 ( –1.57079 to 1.57079). The number of decimal places in the display of the result can be specified with SET DECIMALS.
Return Value
Numeric
Remarks
Use RTOD(В ) to convert radians to degrees.
Example
| В |  Copy Code |
|---|---|
CLEAR ? RTOD(ASIN(0)) && Returns 0.00 STORE 1 to gnArcAngle ? RTOD(ASIN(gnArcAngle)) && Returns 90.00 ? RTOD(ASIN(SQRT(2)/2)) && Returns 45.00 | |
