NAME
logbd64(), logbd128(), logbd32() - decimal exponent functions
SYNOPSIS
DESCRIPTION
The function computes the exponent of the floating point value x. Formally, the return value is the integral part of log base 10 of |x| as
a signed floating point value, for nonzero x.
If x is subnormal, it is treated as though it were normalized, before the exponent is determined.
is a version of it takes a argument and returns a result.
