EPT (1)

returns the value 1 (1 = .1E+1).

EPT (.0234)

returns the value -1 (.0234 = .234E-1).

EPT (X)

If X=.003024, returns the value -2 (.003024 = .3024E-2).

EPT (-231)

returns the value 3 (-231 = -.231E+3).

LET Z=EPT (Y/4)

If Y=100, returns the value 2 (100/4 = 25 = .25E+2) and assigns it to the variable Z.
