.SH NAME

near \- Determine whether two values are roughly equal.
.SH SYNOPSIS
.HP
.B loadrt near [count=\fIN\fB|names=\fIname1\fB[,\fIname2...\fB]]
.SH FUNCTIONS
.TP
\fBnear.\fIN\fB\fR (requires a floating-point thread)

.SH PINS
.TP
.B near.\fIN\fB.in1\fR float in \fR
.br
.ns
.TP
.B near.\fIN\fB.in2\fR float in \fR
.br
.ns
.TP
.B near.\fIN\fB.out\fR bit out \fR

\fBout\fR is true if \fBin1\fR and \fBin2\fR are within a factor of
\fBscale\fR (i.e., for in1 positive, in1/scale <= in2 <= in1*scale), OR
if their absolute difference is no greater than \fBdifference\fR (i.e.,
|in1-in2| <= difference).  \fBout\fR is false otherwise.
.SH PARAMETERS
.TP
.B near.\fIN\fB.scale\fR float rw \fR(default: \fI1\fR)
.br
.ns
.TP
.B near.\fIN\fB.difference\fR float rw \fR(default: \fI0\fR)
