Is their Syntax to show say Pi to 100 decimal places or do you have to set Operations to 100 decimal places and then evaluate a known function for π?
The manual shows Pi_Digits may meet your need. Check out this link to the manual entry.
Thanks, just the ticket. Now I just need to figure out if there’s a generic way to do the same with other irrational/transcendental numbers e.g. √2 to 100 decimal places, e to 90 decimal places etc.
There is not a generic way to show irrational numbers to 100 places in MS. MS uses double precision floating point numbers which is quite fast in calculations and not arbitrary precision numbers which is much slower.
That said, there is an undocumented way to use arbitrary precision integers in MS. Use an @n to invoke arbitrary precision integers. So
Will compete 100 factorial and display all the digits. No all MS functions support it, so it is likely not all that useful too you,
