- 'fpext .. to' Instruction + 'fptrunc .. to' Instruction
+
Syntax:
+ 
-  <result> = fpext <ty> <value> to <ty2>             ; yields ty2
+  <result> = fptrunc <ty> <value> to <ty2>             ; yields ty2
Overview:
-

The 'fpext' extends a floating point value to a larger -floating point value.

+

The 'fptrunc' instruction truncates value to type +ty2.

+
Arguments:
-

The 'fpext' instruction takes a -floating point value to cast, -and a floating point type to cast it to.

+

The 'fptrunc' instruction takes a floating + point value to cast and a floating point type to +cast it to. The size of value must be larger than the size of +ty2. This implies that fptrunc cannot be used to make a +no-op cast.

Semantics:
-

The 'fpext' instruction extends the value from one floating -point type to another. If the type of the value and ty2 are -the same, the instruction is considered a no-op cast because no bits -change.

+

The 'fptrunc' instruction converts a +floating point value from a larger type to a smaller +type. If the value cannot fit within the destination type, ty2, then +the results are undefined.

Example:
-  %X = fpext float 3.1415 to double        ; yields double:3.1415
-  %Y = fpext float 1.0 to float            ; yields float:1.0 (no-op)
+  %X = fptrunc double 123.0 to float         ; yields float:123.0
+  %Y = fptrunc double 1.0E+300 to float      ; yields undefined
