Caché ObjectScript Reference - InterSystems Documentation

Math and Time FunctionsParametersnAn angle in radians ranging from Pi to 2 Pi (inclusive). It can be specified as a value, a variable,or an expression. You can specify the value Pi by using the $ZPI special variable. You canspecify positive or negative values smaller than Pi or larger than 2 Pi; Caché resolve thesevalues to the corresponding multiple of Pi. For example, 3 Pi is equivalent to Pi, negative Piis equivalent to Pi, and zero is equivalent to 2 Pi.ExampleThe following example permits you to compute the cosine of a number:READ "Input a number: ",numIF $ZABS(num)>(2*$ZPI) { WRITE !,"number is a larger than 2 pi" }ELSE {WRITE !,"the cosine is: ",$ZCOS(num)}QUITSee Also• $ZSIN function• $ZARCCOS function• $ZPI special variable$ZCOTCotangent function.$ZCOT(n)ParametersnAn angle in radians.Description$ZCOT returns the trigonometric cotangent of n. The result is a signed decimal number.320 Caché ObjectScript Reference
