| noExp {bigBits} | R Documentation |
Function to convert character-string numbers in exponential notation to "pure" integers.
Description
This is a helper function for base2base. When an input value is a character string with exponential notation, e.g., "2.65e4" , this function rebuilds the character string as a pure integer, e.g., "26500" . Decimal portions are removed.
Usage
noExp(x)
Arguments
x |
An input character string, assumed only to contain numerals 0-9, "+,-,e,E" and the decimal separator character defined in the current locale. |
Details
Both input and output must be base 10, as exponentiation in other bases is outside the current scope of this package.
Value
A character string representing the input as an integer written "longhand," i.e. no exponent. This string will contain only numerals and possibly a lead minus sign in the case of negative inputs.
