Cosecant function.
Synopsis
`\$ZCSC(n)`
Parameter
Description
\$ZCSC returns the trigonometric cosecant of n. The result is a signed decimal number.
Parameter
n
An angle in radians, specified as a nonzero number. It can be specified as a value, a variable, or an expression. Specifying 0 generates an <ILLEGAL VALUE> error; specifying \$DOUBLE(0) generates a <DIVIDE> error. A non-numeric string is evaluated as 0.
Examples
The following example permits you to compute the cosecant of a number:
```   READ "Input a number: ",num
IF num=0 { WRITE !,"ILLEGAL VALUE: zero not permitted" }
ELSE {
WRITE !,"the cosecant is: ",\$ZCSC(num)
}
QUIT```
The following example compares the results from Caché fractional numbers (\$DECIMAL numbers) and \$DOUBLE numbers. In both cases, the cosecant of pi/2 is exactly 1:
```  WRITE !,"the cosecant is: ",\$ZCSC(\$ZPI)
WRITE !,"the cosecant is: ",\$ZCSC(\$DOUBLE(\$ZPI))
WRITE !,"the cosecant is: ",\$ZCSC(\$ZPI/2)
WRITE !,"the cosecant is: ",\$ZCSC(\$DOUBLE(\$ZPI)/2)
WRITE !,"the cosecant is: ",\$ZCSC(\$DOUBLE(\$ZPI/2))```
