Filtering for IEEE Values
If you are writing an expression, you can use the following Boolean functions
to check for a particular type of value:
IEEE Intrinsic Meaning
$is_denorm(value) Is a denormalized number, either positive or negative
$is_finite(value) Is finite
$is_inf(value) Is Infinity, either positive or negative
$is_nan(value) Is a NaN (Not a number), either quiet or signaling
$is_ndenorm(value) Is a negative denormalized number
$is_ninf(value) Is negative Infinity
$is_nnorm(value) Is a negative normalized number
$is_norm(value) Is a normalized number, either positive or negative
$is_nzero(value) Is negative zero
$is_pdenorm(value) Is a positive denormalized number
$is_pinf(value) Is positive Infinity
$is_pnorm(value) Is a positive normalized number
$is_pzero(value) Is positive zero
$is_qnan(value) Is a quiet NaN
$is_snan(value) Is a signaling NaN
$is_zero(value) Is zero, either positive or negative
