Overview

This cop checks for division with integers coerced to floats. It is recommended to either always use fdiv or coerce one side only. This cop also provides other options for code consistency.

Examples:

EnforcedStyle: single_coerce (default)

# bad
a.to_f / b.to_f

# good
a.to_f / b
a / b.to_f

EnforcedStyle: left_coerce

# bad
a / b.to_f
a.to_f / b.to_f

# good
a.to_f / b

EnforcedStyle: right_coerce

# bad
a.to_f / b
a.to_f / b.to_f

# good
a / b.to_f

EnforcedStyle: fdiv

# bad
a / b.to_f
a.to_f / b
a.to_f / b.to_f

# good
a.fdiv(b)
