My Rexx [tools] directory, on path, has many tiny programs like this.
/* sin.rex */
call RxFuncAdd"MathLoadFuncs","rxmath","MathLoadFuncs"
call MathLoadFuncs
return rxcalcsin(arg(1))
Mostly used from command line as (for example):
say sin(45)
which uses this:
/* say.rex -- effect Rexx SAY */
interpret 'say' arg(1)
Would be nice if there were something architected/defined. Recommendations for
trig functions are now in the IEEE 754 standard, btw.
