Process an Array in Ruby

[OllieMarshall92]

Hi All,

Basically I want to find the sin([array]) (sine of each value in the array) and then export the array from ruby.

I can find the sine of a float but my code wont do the same to an array. Ruby comes up with an error something like "cant convert array to float".
I think I may need to iterate through the array, processing one at a time but I cant work out how to do that.

With "myarr" as the array that contains the data

Code: Select all

na = myarr.map { |v| Math.sin(v) }

With RAD2DEG and RAD2GRAD module.

Thanks, both of you.

My input is in degrees, how do I format it so if I put 180 in I get a 0 out? e.g. sin(180) = 0
