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, and negativePi is equivalent to Pi.ExampleThe following example permits you to compute the sine of a number:READ "Input a number: ",numIF $ZABS(num)>(2*$ZPI) { WRITE !,"number is a larger than 2 pi" }ELSE {WRITE !,"the sine is: ",$ZSIN(num)}QUITSee Also• $ZCOS function• $ZARCSIN function• $ZPI special variable$ZSQRReturns the square root of a specified number.$ZSQR(n)ParameternAny positive number, or zero. (The null string and non-numeric string values aretreated as a zero.) Can be specified as a value, a variable, or an expression.Description$ZSQR returns the square root of n. It returns the square root of 1 as 1. It returns the squareroot of 0 and the square root of a null string ("") as 0. Specifying a negative number invokes374 Caché ObjectScript Reference
