The error conditions that can occur for mathematical functions
are described below.
-.SS Domain Error
+.SS Domain error
A
.I domain error
occurs when a mathematical function is supplied with an argument whose
and an "invalid"
.RB ( FE_INVALID )
floating-point exception is raised.
-.SS Pole Error
+.SS Pole error
A
.I pole error
occurs when the mathematical result of a function is an exact infinity
and a "divide-by-zero"
.RB ( FE_DIVBYZERO )
floating-point exception is raised.
-.SS Range Error
+.SS Range error
A
.I range error
occurs when the magnitude of the function result means that it
A floating result
.I overflows
-if the result is finite,
+if the result is finite,
but is too large to represented in the result type.
When an overflow occurs,
the function returns the value
