values to the corresponding multiple of Pi. For example, 3 Pi is equivalent to Pi, and negativePi is equivalent to Pi.ExampleThe following example permits you to compute the secant of a number:READ "Input a number: ",numIF $ZABS(num)>(2*$ZPI) { WRITE !,"number is a larger than 2 pi" }ELSE {WRITE !,"the secant is: ",$ZSEC(num)}QUITSee Also• $ZCSC function• $ZPI special variable$ZSIN$ZSINReturns the trigonometric sine of the specified angle value.$ZSIN(n)ParametersnAngle in radians ranging from Pi to 2 Pi (inclusive). Other supplied numeric valuesare converted to a value within this range.Description$ZSIN returns the trigonometric sine of n. The result is a signed decimal number rangingfrom 1 to -1 (see note).Note:$ZSIN (like all trigonometric functions) calculates its values based on pi roundedto the number of available decimal digits. Therefore, the value returned by$ZSIN($ZPI) is .000000000000000000462644 and $ZSIN($ZPI*2) is–.00000000000000000092529. For this reason you should not perform limit testscomparing these returned values to 0. $ZSIN(0) returns 0.Caché ObjectScript Reference 373
