Instance Method Details

#to_d(precision = 0) ⇒ 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. When precision is set to 0, the number of digits to represent the float being converted is determined automatically. The default precision is 0.

require 'bigdecimal'
require 'bigdecimal/util'

0.5.to_d         # => 0.5e0
1.234.to_d       # => 0.1234e1
1.234.to_d(2)    # => 0.12e1
