---- had issues due to an edge case before:
------ eg: 49518.81665 - 22399.4358
------ produces: 47278.87307
------ correct: 27119.38085
---- this happened when ${#1} > ${#2}
---- if $2 contains decimals
-- tester:
---- now exits `1` if answer is "false"
-- division
---- debugging on going

--- psh-fractional -- fractional math in pure sh, successor to psh-float-micro --- Current Status -- addition ~85% working ---- has some odd issues with decimals ---- has issues with "Illegal number" ------ eg: 18471.81672 + 27540.27237 ---- will debug at later date -- subtraction ~90% working ---- had issues due to an edge case before: see last commit ---- has an issue where $e in rad() somehow becomes malformed ------ eg: 23019.18605 - 1139 ------ produces: 11629.18605 ------ correct: 21880.18605 ---- current method uses a system of removing the decimal from $1 & $2 ---- and then subtracting them; (m1-m2) ---- the issue is likely in rad() as $((m1-m2)) is correct before ---- being handed to rad() -- multiplication 100% working ---- length issues when comparing to bc (produces additional decimals) ------ I am not going to attempt to fix this ------ it's really not an issue -- division ~90% working ---- may sometimes produce to many decimals ------ this will not be fixed ---- rarely places decimals in wrong places ------ eg: 324.81478 / 21715 ------ produces: 1.49580833525212986414 ------ correct: 0.01495808335252129864 ---- Some odd edge case with $dp is causing this... ---- debugging ongoing --- Outer Usage -- it is recommended to use this library with psh-fc -- if you wish to compare numbers that it produces -- as decimal numbers are not considered numbers by posix sh ---- https://dicksdeathabove.xyz/~mia/psh-fc --- Tester -- a tester is present at ./tester; it is ofc not pure sh as it compares with bc -- additionally using it requires that $RPATH is set to ?/psh-prng/ran ---
