R2SW

Parameters

r	real	The number to be converted.
width	integer	The width of the string. If the width of the resulting conversion is too small the string will be filled with spaces. Use 0 for no padding.
precision	integer	The amount of decimal places. The minimum possible precision is 1 (automatically set).

comment

Returns a string representation for real r with precision digits and width. The real is correctly rounded to nearest to fit within the precision.

Lua: Raises an error if r is null.

Works similar to C/C++ printf, but does not support negative width (left-align with right padding).

Example (Lua):

R2SW(31.1235, 5, 3) == "31.124"
R2SW(1, 5, 0) == "  1.0" --> two spaces followed by number

note

See: R2S for a simple converter with preset values.
