The code you supplied and put into EXAMPLE 2 below works OK. EXAMPLE 1
below shows a similar rounding problem that can occur with the MC format
function. The format function with a format of %6.2f rounds 1.3350 to 1.33,
whereas round(1.3350, 2) returns 1.34. My summer students discovered this
last week in homework 1 with similar behavior of MC format function and True
Basic's PRINT USING instruction. None of this may have solved your problem,
so good luck!

# EXAMPLE 1: script of button that displays output in fld 3
# DISPLAY IN FLD 3:
price = 133.50
tax = 1.33
total = 134.84
total 2 = 134.83
total 3 = 134.84
on mouseUp
put 133.50 into price
put 1.3350 into tax
put tax + price into total
put format ("price = %6.2f", price) into line 1 of fld 3
put format ("tax = %6.2f", tax) into line 2 of fld 3
put format ("total = %6.2f", total) into line 3 of fld 3
put format ("%6.2f", tax) into tax2
put "total 2 = " & tax2 + price into line 4 of fld 3
put round(tax, 2) into tax2
put "total 3 = " & tax2 + price into line 5 of fld 3
end mouseUp

# put round(temp_category_total, 2) into category_total
