bignum-arith {bignum} | R Documentation |
biginteger and bigfloat vectors support the standard arithmetic operations. The base R documentation can be found at Arithmetic.
These arithmetic operations are type-stable, which means the output type depends only on the input types (not the input values). A biginteger vector is returned when the result must be an integer (e.g., addition of two integers). Otherwise a bigfloat vector is returned.
The following table summarizes the return type for each combination, where "integer-like" refers to integer and biginteger vectors and "float-like" refers to double and bigfloat vectors.
Input 1 | Operator | Input 2 | Result | |
Integer-like | +, -, *, ^, %% | Integer-like | -> | biginteger |
Integer-like | +, -, *, ^, %% | Float-like | -> | bigfloat |
Float-like | +, -, *, ^, %% | Integer-like | -> | bigfloat |
Float-like | +, -, *, ^, %% | Float-like | -> | bigfloat |
Any | / | Any | -> | bigfloat |
Any | %/% | Any | -> | biginteger |
