Bignumber floor issue or misunderstanding of relTol ? #3247
Open
Description
Hello, I don't know well if it's an issue or if I'm doing something wrong : (math.js version 13.0.3)
math.config({
number: "BigNumber", // Default type of number:
// 'number' (default), 'BigNumber', or 'Fraction'
precision: 509, // Number of significant digits for BigNumbers
relTol: 1e-60,
absTol: 1e-63
});
//pi*10^60
math.multiply(math.pi, math.pow(math.bignumber(10),math.bignumber(60))).toFixed()
//'3141592653589793238462643383279502884197169399375105820974944.5923078164062862089986280348253421170679821480865132823066470938446095505822317253594081284811174502841027019385211055596446229489549303819644288109756659334461284756482337867831652712019091456485669234603486104543266482133936072602491412737245870066063155881748815209209628292540917153643678925903600113305305488204665213841469519415116094330572703657595919530921861173819326117931051185480744623799627495673518857527248912279381830119491298336734'and then because of relTol of 1e-60 when you floor it it send a wrong result :
math.floor(math.multiply(math.pi, math.pow(math.bignumber(10),math.bignumber(60)))).toFixed()
//'3141592653589793238462643383279502884197169399375105820974945' instead of
//'3141592653589793238462643383279502884197169399375105820974944'what should I do to get correct number ?
i tried this :
math.config({
number: "BigNumber", // Default type of number:
// 'number' (default), 'BigNumber', or 'Fraction'
precision: 509, // Number of significant digits for BigNumbers
relTol: 1e-503,
absTol: 1e-508
});but it convert then 1e-503 to 0 and then get this error (because relTol = 0 then)
Error: Relative tolerance must be greater than 0
thank you :)
