For Projected Coordinate System Makassar / NEIEZ
Parameters:
Ellipsoid Bessel 1841 a = 6377397.155 m 1/f = 299.15281
then e = 0.08169683
Latitude of natural origin = 00°00'00"N = 0.0000000 rad
Longitude of natural origin = 110°00'00"E = 1.91986218 rad
Scale factor at natural origin ko = 0.997
False Eastings FE = 3900000.00 m
False Northings FN = 900000.00 m
Forward calculation for:
Latitude = 3°00'00.00"S = -0.05235988 rad
Longitude = 120°00'00.00"E = 2.09439510 rad
gives
Easting E = 5009726.58 m
Northing N = 569150.82 m
Reverse calculation for same easting and northing first gives :
t = 1.0534121
chi = -0.0520110
Latitude = 3°00'00.000"S
Longitude = 120°00'00.000"E

Mercator (variant A)
Note that in these formulas the parameter latitude of natural origin (latO) is not used. However for this Mercator (variant A) method the EPSG dataset includes this parameter, which must have a value of zero, for completeness in CRS labelling.
Note: These formulas have been transcribed from EPSG Guidance Note #7-2. Users are encouraged to use that document rather than the text which follows as reference because limitations in the transcription will be avoided.
The formulas to derive projected Easting and Northing coordinates are:
E = FE + a*ko(lon - lonO)
N = FN + a*ko* ln{tan(pi/4 + lat/2)[(1 - esin(lat))/(1 + esin(lat))]^e/2} where symbols are as listed above and logarithms are natural.
The reverse formulas to derive latitude and longitude from E and N values are:
lat = chi + (esq/2 + 5e^4/24 + e^6/12 + 13e^8/360) sin(2chi)
+ (7e^4/48 + 29e^6/240 + 811e^8/11520) sin(4chi)
+ (7e^6/120 + 81e^8/1120) sin(6chi) + (4279e^8/161280) sin(8chi)
where chi = pi/2 - 2 arctan t
t = B^((FN-N)/(a*ko))
B = base of the natural logarithm, 2.7182818...
and for the 2 SP Case, ko is calculated as for the forward transformation above.
lon = ((E - FE)/(a*ko)) + lonO

The latitude of the point from which the values of both the geographical coordinates on the ellipsoid and the grid coordinates on the projection are deemed to increment or decrement for computational purposes. Alternatively it may be considered as the latitude of the point which in the absence of application of false coordinates has grid coordinates of (0,0).

Since the natural origin may be at or near the centre of the projection and under normal coordinate circumstances would thus give rise to negative coordinates over parts of the mapped area, this origin is usually given false coordinates which are large enough to avoid this inconvenience. The False Easting, FE, is the value assigned to the abscissa (east or west) axis of the projection grid at the natural origin.
