NSum
(Built-in Mathematica Symbol) NSum[f, {i, i_min, i_max}] gives a numerical approximation to the sum \[Sum]i = i_min i_max f.NSum[f, {i, i_min, i_max, di}] uses a step di in the sum.
NumberFormat is an option for NumberForm and related functions that specifies how the mantissa, base, and exponent should be assembled into a final print form.
NumberSeparator is an option for NumberForm and related functions which gives the string to insert at breaks between digits.
NumberSigns is an option for NumberForm and related functions which gives strings to use as signs for negative and positive numbers.
PaddedForm[expr, n] prints with all numbers in expr padded to leave room for a total of n digits. PaddedForm[expr, {n, f}] prints with approximate real numbers having exactly ...
