Everyone can write???? In 20 minutes???? I'm sure there are hardly any
Pascal programmers out there who write mathematical programs who know,
or even want to know, anything about assembler - let alone embedding
inline 387 code. MATH387 is there to make their lives easier - it is
just as simple to code trig functions using MATH387 as without it, but
it is MUCH faster (and significantly faster than some of the other
"competition", e.g. MATHLIB2).
About the price: point taken. I don't live in the US, so I have
difficulty conceptualising a "value" in dollars. $20 just seems to be
the norm for many, many shareware programs out there - small and
large. Besides, for most people, the value has more to do with
usefulness than how many routines are provided. My gage of usefulness
for MATH387 is the absolute fastest possible performance - bar
nothing.
What price do you think would be reasonable?
