float math issues in 1.2.5

[gMakaan]

Try this formulas without setting <<formulaPrecision>> and <<formulaFixed>>:

• 0.99999 = 1
• 0.999999 = 0.1 (wrong result at 6+ digits after point, but using <<formulaPrecision>> and <<formulaFixed>> can fix it)
• 0.999999/1 = 0.1
• trunc(1,1) = 0.9
• trunc(1,5) = 0.99999
• trunc(1,6) = 0.10 (with parameter 7 and more it returns same result 0.10)
• trunc(-1,1) = -0.9000000000000001
• trunc(-1,2) = -0.9900000000000005 (others in similar manner)
• round(1,19) = 0.10
• round(1,37) = 0.10 (here may be more such "wrong numbers")
• round(-1,1) = -1.0000000000000002
• round(-1,2) = -1.0000000000000004 (with parameter 3 and more last numbers changed via floating point precision errors)
• round(-1,14) = -0.9999999999999958
• round(-1,15) = -1.0000000000000002 (16, 17, 18 param value return -1 as it must)
• round(-1,19) = -0.9999999999999999 (but it already out of bounds)
