3−16PCP Reference Manual@SNH(expression)Returns the hyperbolic sine of expression as a floating−point value.Example:HSINE .EQU @SNH(VAL);hyperbolic sine@SQT(expression)Returns the square root of expression as a floating−point value. expressionmust be positive.Example:SQRT1 .EQU @SQT(3.5) ;SQRT1 = 1.870829SQRT2 .EQU @SQT(16) ;SQRT2 = 4ASSEMBLY LANGUAGE@SUB(string,expression1,expression2)Returns the substring from string as a string. Expression1 is the startingposition within string, and expression2 is the length of the desired string.The assembler issues an error if either expression1 or expression2 exceedsthe length of string. Note that the first position in a string is position 0.Example:.DEFINE ID "@SUB(’PCP−assembler’,4,9)" ;ID =’assembler’@TAN(expression)Returns the tangent of expression as a floating−point value.Example:TANGENT .SET @TAN(1.0) ;TANGENT = 1.5574077@TNH(expression)Returns the hyperbolic tangent of expression as a floating−point value.Example:HTAN .SET @TNH(1) ;HTAN = 0.76159415595
