PNut_v51 adds exponential floating-point operators to Spin2 with a few minor enhancements and a bug fix. Here's what's new in v50:

• New floating-point operators: POW, LOG2, EXP2, LOG10, EXP10, LOG (natural log) and EXP (e-to-the-power-of-x).

• SIZEOF() can now be used in DAT blocks to get sizes of structures in bytes.

• Long variables within structures can now be used as method pointers.

• The syntax for ignoring multiple return values from methods has changed, since it had a stack bug and couldn't been successfully used by anyone. Instead of '_(number_of_longs_toignore)', it now uses brackets: '[number_of_longs_to_ignore]'.

A few bugs were found and fixed that had been in several versions, up to v51. One bug was causing columns not to be counted correctly for "object.method" instances and the other was not allowing "[++/--]structure_ptr" to be used as a parameter, due to some parsing oversight. These have both been fixed and a new v51a has been added below.
