Answer 2

Most likely they are a bit different implementations resulting in floating-point precision problems.
math.log10(1000) = 3.0
math.log(1000, 10)= 2.99999999996

Both are *equal*, just not floating-point equal :)

Answer 3

math.log(20, 5)

Answer 4

can you tell me How to print 20log5?
20*math.log10(5)? Is this correct?

Answer 5

there is 4 log modules...
1. log(value , base)
2. log10(value)
3. log2(value)
4. log1p(value)

1 is general...default base is 'e'
2 is fixed base 10
3 is fixed base 2
4 is fixed bade 'e' but doing logarith of (1+value)-----p denotes plus
