subtract
Perform precise subtraction of two numbers, including integers or fractions, with 64-bit floating point accuracy. Returns the result as a 64-bit float for reliable mathematical computations.
Instructions
Subtracts two numbers with 64 bit floating point precision and returns a 64 bit float. For example, subtracting 5 from 10 would return 5.0. You can also use fractions if you want to, like 1/2 for number_1 and 1/3 for number_2.
