#to_d(precision = Float::DIG+1) ⇒ Object

call-seq:

float.to_d             -> bigdecimal
float.to_d(precision)  -> bigdecimal

Returns the value of float as a BigDecimal. The precision parameter is used to determine the number of significant digits for the result (the default is Float::DIG).

require 'bigdecimal'
require 'bigdecimal/util'

0.5.to_d         # => 0.5e0
1.234.to_d(2)    # => 0.12e1
